The Effect of Masks and Respirators on Acoustic Voice Analysis During the COVID-19 Pandemic. J Voice 2024; 38:798.e1-798.e6. [PMID: 34961655 PMCID: PMC8627850 DOI: 10.1016/j.jvoice.2021.11.014] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2021] [Revised: 10/31/2021] [Accepted: 11/23/2021] [Indexed: 12/25/2022]
Abstract
OBJECTIVES World Health Organization declared the coronavirus disease (COVID-19) as a global pandemic on March 11, 2020. The aim of this study was to determine the effectiveness and reliability of voice analysis performed with surgical masks and respirators during the pandemic and to discuss its routine applicability. METHODS This prospective study included 204 patients who applied to our clinic between the ages of 18 and 55, whose preoperative SARS-Cov-2 PCR tests were negative. Voice analyses were performed on each patient without a mask, with a surgical mask and with a valved face-filtering piece-3 (FFP3) respirator respectively. The F0, shimmer, jitter, s/z ratio, maximum phonation time and harmonic/noise ratio (HNR) values obtained from the voice analyses were compared with each other. RESULTS No significant difference was found in terms of F0, Jitter, Shimmer, HNR, s/z and maximum phonation time values in the voice analyses performed without a mask and with a surgical mask. With an FFP3, a significant difference was found in only the Shimmer and HNR values compared to the other analysis values. When we look at the data with sex distinction, in the group of female and male patients, when the data of voice analysis obtained in three situations were compared, different results were obtained from the female and male group. CONCLUSION In conclusion, it should be decided by the physician to perform the voice analysis with a surgical mask or with an FFP3, considering the clinically desired parameters.

Critical swallowing functions contributing to dysphagia in patients with recurrent laryngeal nerve paralysis after esophagectomy. Esophagus 2024; 21:111-119. [PMID: 38294588 DOI: 10.1007/s10388-023-01041-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/22/2023] [Accepted: 12/28/2023] [Indexed: 02/01/2024]
Abstract
BACKGROUND Recurrent laryngeal nerve paralysis (RLNP) after esophagectomy can cause aspiration because of incomplete glottis closure, leading to pneumonia. However, patients with RLNP often have preserved swallowing function. This study investigated factors that determine swallowing function in patients with RLNP. METHODS Patients with esophageal cancer who underwent esophagectomy and cervical esophagogastric anastomosis were enrolled between 2017 and 2020. Videofluoroscopic examination of swallowing study (VFSS) and acoustic voice analysis were performed on patients with suspected dysphagia including RLNP. Dysphagia in VFSS was defined as score ≥ 3 of the 8-point penetration-aspiration scale VFSS and acoustic analysis results related to dysphagia were compared between patients with and without RLNP. RESULTS Among 312 patients who underwent esophagectomy, 74 developed RLNP. The incidence of late-onset pneumonia was significantly higher in the RLNP group than in the non-RLNP (18.9 vs. 8.0%, P = .008). Detailed swallowing function was assessed by VFSS in 84 patients, and patients with RLNP and dysphagia showed significantly shorter maximum diagonal hyoid bone elevation (10.62 vs. 16.75 mm; P = .003), which was a specific finding not seen in patients without RLNP. For acoustic voice analysis, the degree of hoarseness was not closely related to dysphagia. The length of oral intake rehabilitation for patients with and without RLNP was comparable if they did not present with dysphagia (8.5 vs. 9.0 days). CONCLUSIONS Impaired hyoid bone elevation is a specific dysphagia factor in patients with RLNP, suggesting compensatory epiglottis inversion by hyoid bone elevation is important for incomplete glottis closure caused by RLNP.

Evaluation of Size, Laterality, and Location of Unilateral Vocal Fold Lesions on Voice Quality. J Voice 2024; 38:472-478. [PMID: 34740499 DOI: 10.1016/j.jvoice.2021.09.013] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2021] [Revised: 09/10/2021] [Accepted: 09/16/2021] [Indexed: 11/20/2022]
Abstract
INTRODUCTION The presence of a vocal fold mass implies high mechanical stress at the vocal fold base during vibration and an impaired glottic closure. However, evidence about its potential effects on diagnostic tools used in voice evaluation is lacking. We aimed to evaluate the impact of the location, laterality, and size of a unilateral unique vocal fold lesion on patient self-assessment questionnaires, acoustic-aerodynamic voice measures, and perceptual voice evaluation (GRBAS scale). METHODS A retrospective chart review involving patients with a diagnosis of a unique unilateral vocal fold lesion and a complete voice evaluation was performed. A total of 58 patients were enrolled and demographics, characteristics of the vocal fold lesion (size, laterality, and location), self-assessment questionnaires, acoustic-aerodynamic measures, and perceptual evaluation (GRBAS scale) were analyzed. Pearson correlation and ANOVA analysis were completed to evaluate the correlation between the clinical characteristics of the vocal fold mass and self-assessment questionnaires, and to compare the level of significance for the differences between the continuous variables between groups of patients once stratified according to the location or laterality of the vocal fold mass. RESULTS Glottal Function Index was found to correlate with the location of the vocal fold mass (P < 0.05), however, no correlation was found when evaluating the Reflux Symptom Index or the Voice Handicap Index (P > 0.05). Patients with a lesion located in the anterior-middle 2/3 of the vocal fold were found to have a higher mean Glottal Function Index and (G) component of the GRBAS scale (P < 0.05). No differences were observed when analyzing the remaining self-assessment questionnaires or the acoustic-aerodynamic voice measures according to size, location, or laterality of the vocal fold lesion (P > 0.05). CONCLUSION The size and location of unilateral vocal fold lesions were found to have no effect on the majority of measures analyzed in this study. This is the first study we know of to assess the effect that laterality of the vocal fold lesion may have on the self-assessment questionnaires, audio-perceptual, and acoustic-aerodynamic measures included in this study. Our study found no significant differences in regard to laterality. This may indicate that other factors (eg, stiffness of lesion, amount of extraneous muscle tension, etc) could have more of an impact on audio-perceptual, self-assessment questionnaires, and acoustic-aerodynamic measures. Further research with larger cohort sizes and possibly prospective analysis is needed.

Abstract
OBJECTIVES To study the voice acoustic parameters of congenitally deaf children with delayed access to sounds due to late-onset cochlear implantation and to correlate their voice characteristics with their auditory performance. METHODS The study included 84 children: a control group consisting of 50 children with normal hearing and normal speech development; and a study group consisting of 34 paediatric cochlear implant (CI) recipients who had suffered profound hearing loss since birth. According to speech recognition scores and pure-tone thresholds, the study group was further subdivided into two subgroups: 24 children with excellent auditory performance and 10 children with fair auditory performance. The mean age at the time of implantation was 3.6 years for excellent auditory performance group and 3.2 years for fair auditory performance group. Voice acoustic analysis was conducted on all study participants. RESULTS Analysis of voice acoustic parameters revealed a statistically significant delay in both study groups in comparison to the control group. However, there was no statistically significant difference between the two study groups. DISCUSSION Interestingly, in both excellent and fair performance study groups, the gap in comparison to normal hearing children was still present. While late-implanted children performed better on segmental perception (e.g. word recognition), suprasegmental perception (e.g. as demonstrated by objective acoustic voice analysis) did not progress to the same extent. CONCLUSION On the suprasegmental speech performance level, objective acoustic voice measurements demonstrated a significant delay in the suprasegmental speech performance of children with late-onset CI, even those with excellent auditory performance.

The Voice Range Profile-A Shortened Protocol Pilot Study. J Voice 2023; 37:682-693. [PMID: 34099353 DOI: 10.1016/j.jvoice.2021.04.010] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2021] [Revised: 04/08/2021] [Accepted: 04/15/2021] [Indexed: 11/23/2022]
Abstract
INTRODUCTION Voice production is a complex process involving the coordination of various anatomical structures and physiologic systems. The Voice Range Profile (VRP) is an established acoustic measure for evaluating voice production that examines minimum and maximum intensity across the frequency range. This pilot study sought to establish a consistent, efficient, and accessible VRP elicitation method. One primary research question was addressed: Does the proposed Short method provide at least as much information as a full, discrete-steps method, which is generally accepted in the literature? METHODS In this quasi-repeated measures design, twenty-four singers completed a full VRP based on accepted methods from the literature, and the same participants returned within one to three weeks to complete the proposed Short VRP protocol. The full VRP consisted of steady state productions at every semitone within a participant's range for both minimum and maximum intensities. The Short VRP consisted of steady state productions at every octave and perfect fifth across the semitone range for both minimum and maximum intensities. Additional sampling was completed between points when a 7 dB or greater difference was found between consecutive points. Analysis compared each protocol's average elicitation time differences, average semitone range differences, visual examination of the average VRP graph, and examination of average intensity differences between protocols at specific semitone points. Male and female results were analyzed separately. RESULTS The proposed Short protocol produced similar or better intensity ranges when compared with the accepted full elicitation method. The Short protocol produced intensities with 95% or greater similarity to the Full Protocol for male maximum intensity curve, female minimum intensity curve, and female maximum intensity curve. CONCLUSIONS When compared with a Full VRP, a Short VRP protocol appears to generate similar minimum and maximum intensity curves allowing for a time-efficient substitute.

Introduction of Voice Type Component (VTC) as an Effective Acoustic Voice Analysis Method in Tele-evaluation. J Voice 2023:S0892-1997(23)00215-1. [PMID: 37544815 DOI: 10.1016/j.jvoice.2023.07.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2023] [Revised: 07/06/2023] [Accepted: 07/06/2023] [Indexed: 08/08/2023]
Abstract
OBJECTIVE Telepractice in voice health care and evaluation services has attracted much attention in recent years. Multiple studies have proven the effectiveness of voice therapy with telepractice. However, voice evaluations are still mostly conducted in person due to the lack of sensitive acoustic analysis methods. METHODS This study examined various acoustic analysis methods for voice evaluation in telepractice. Eighteen female elementary school teachers with self-reported voice disorders volunteered to participate in the study. Speech samples were collected before and after the interventions using two voice sampling methods concurrently. One set of data was collected using the traditional voice sample collection method by the therapist in person. The second set of data was collected on the same speech samples using the clients' own smartphones, and the collected voice samples were later sent to the researcher for further acoustic analysis. The voice type component (VTC) measurement represented the proportion of different VTCs in a voice by measuring the chaos and intrinsic dimension. RESULTS Voice analyses were conducted on both sets of data, and the correlation between the two sampling procedures was analyzed. It appears that the VTC could be a more reliable method for producing acoustic analysis results with voice samples collected from smartphones compared to other objective voice assessment procedures. This reliability has been demonstrated via statistical analysis, including correlation coefficient, pairwise t test, d-prime, and area under the curve. The results of this study highlighted the VTC as an effective and accurate acoustic analysis method in tele-evaluation. CONCLUSIONS This feasible voice sampling method, which utilizes participants' own smartphones, will reduce barriers to accessing limited voice specialists due to distance and will decrease the cost of care by minimizing expenses associated with travel and additional equipment for voice sampling. Ultimately, this approach will enhance the effectiveness of voice care delivered through telepractice to patients in remote and underserved areas.

Effect of Chronic Cough on Voice Measures in Patients With Dysphonia. J Voice 2023; 37:251-256. [PMID: 33431203 DOI: 10.1016/j.jvoice.2020.12.025] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2020] [Revised: 12/11/2020] [Accepted: 12/15/2020] [Indexed: 11/22/2022]
Abstract
INTRODUCTION Measuring the impact of chronic cough on voice quality can be difficult and challenging in daily practice. Evidence about its potential effects on diagnostic tools used in voice evaluation is lacking. We hypothesized that the presence of chronic cough plays a role in patients' perception of dysphonia severity, leading to a mismatch between the subjective, objective, and perceptual evaluations. METHODS A retrospective chart review involving patients with a diagnosis of dysphonia and a complete speech voice evaluation was performed. A total of 311 patients were stratified into two different groups according to the presence of chronic cough. A total of 151 patients were assigned to the dysphonia and chronic cough group, while 160 patients were assigned to the dysphonia only group. During the initial evaluation, patients completed the Voice Handicap Index (VHI)-30, Glottal Function Index (GFI), and Reflux Symptoms Index (RSI). Voice evaluation also included aerodynamic/acoustic measures and the application of the GRBAS scale by a speech-language specialist. A paired t test and a linear regression analysis were used to compare subjective, perceptual, and aerodynamic/acoustic measures in both groups. RESULTS The mean VHI-30 and GFI were elevated in both groups but significantly lower among patients with dysphonia and chronic cough when compared to patients with dysphonia only (P= 0.01). Additionally, a significantly higher RSI was found among patients with dysphonia and chronic cough (P< 0.01). No difference in aerodynamic/acoustic measures was found between groups (P> 0.05). Our linear regression model demonstrated a significant effect of the presence of chronic cough on the VHI-30, RSI, and GFI questionnaires (P< 0.05). Our model also found that the VHI-30 is a significant predictor for the (G), (B), (A), and (S) components of the GRBAS scale (P< 0.05). CONCLUSION The presence of chronic cough has a significant impact on the different patient-reported outcome measures, including VHI-30, RSI, and GFI. The use of VHI-30 as a predictor for the GRBAS scale reinforces the importance of subjective and perceptual assessment among patients with voice disorders and establishes a new area for exploration.

Abstract
Acoustic voice analysis is still a valuable technique which enables voice clinicians to compare voices to differentiate them into normal and abnormal. The present study was undertaken to standardize acoustic voice parameters in normal healthy adult individuals and gender comparison among them and also acoustic voice analysis of pathological voices and it's comparison with normal healthy voices. Voice samples of vowels /a/, /i/ and /u/ of 80 normal healthy adults (males = 40, females = 40) of control group and 40 patients with dysphonic voice of case group collected and acoustic voice parameters were extracted by using Praat software. There were statistically significant higher values of fundamental frequency (F0) in females, while jitter local (%), shimmer local (%) and harmonic to noise ratio (HNR) had no gender differences in normal healthy voices. Pathological voices of case group subjects with laryngeal pathologies had statistically significant higher values of jitter local (%), shimmer local (%) and lower values of HNR as compare to normal healthy voices of control group. Objective voice analysis by using Praat software is convenient, reliable and cost effective method. This study establishes normative acoustic voice parameters in normal healthy adults. There are no gender differences in adult healthy voices except fundamental frequency (F0), which is higher in females. Patients who are with dysphonic voices due to laryngeal pathologies had altered values of acoustic parameters compared to normophonic adults and clinicians can precisely differentiate pathological voices from normophonics.

Acoustic Analysis of Voice in Laryngopharyngeal Cancers Pre and Post Radiotherapy. Indian J Otolaryngol Head Neck Surg 2022; 74:1973-1978. [PMID: 36452640 PMCID: PMC9701928 DOI: 10.1007/s12070-020-01934-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2020] [Accepted: 06/23/2020] [Indexed: 12/01/2022] Open
Abstract
Laryngopharyngeal cancers are one of the most commonly diagnosed head and neck malignancies frequently presenting primarily with change in voice. Radiotherapy being the main modality of treatment for early cancers continues to affect voice. Hence, acoustic analysis of the voice offers quantifiable values of several parameters delineating the obvious effect of the therapy. A total number of 60 patients, diagnosed with laryngopharyngeal cancers undergoing radiotherapy underwent acoustic voice assessment using Dr. speech software pre-treatment and at 1 and 3 months post radiotherapy. Data analysis was done using Mann-Whitney test and Wilcoxon signed rank test and a significant p value was obtained. The results of the study showed fundamental frequency (F0) and noise to harmonic ratio (NHR) to be the most affected in comparison to Jitter and Shimmer. The F0 and NHR values across baseline evaluation, first month and third month follow up showed a steady deterioration which was significant. The deterioration noted from the first to third month was not statistically significant. Across genders both F0 and NHR deterioration is more in males than in females. Radiotherapy causes definitive alterations in some acoustic measures of voice, which make the voice disharmonic and hoarse with contribution of harshness and breathiness. The effect is more pronounced on vocal parameters that are structure and projection based as evidenced by deterioration in values noted in F0 and NHR. Persistent deteriorated acoustic parameters for a longer duration of time are more likely which emphasizes the need for early voice rehabilitation.

A Comparison of Healthy and Disordered Voices Using Multi-Dimensional Voice Program, Praat, and TF32. J Voice 2022:S0892-1997(22)00011-X. [PMID: 35246346 DOI: 10.1016/j.jvoice.2022.01.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2021] [Revised: 01/06/2022] [Accepted: 01/10/2022] [Indexed: 10/19/2022]
Abstract
PURPOSE Instrumental voice assessment plays a critical role in identifying vocal issues and for documenting treatment outcomes. The reported voice data, however, are sensitive to the algorithm used by each acoustic analysis software program (AASP) to analyze the corresponding waveform. In the present study, five acoustic measures were compared across healthy speakers and speakers with dysphonia for three AASPs commonly used in research, education, and clinical practice: Multidimensional Voice Program (MDVP) by Computerized Speech Lab, Praat, and TF32. MATERIALS AND METHODS Sustained vowel phonations for the quantal vowels /ɑ/, /i/, and /u/ were analyzed for 80 speakers with organic dysphonia and 60 age- and sex-matched healthy controls. Descriptive, inferential, and correlation data are reported for mean fundamental frequency (mean F0), standard deviation of fundamental frequency (SD F0), short-term perturbation measures of jitter and shimmer, and harmonic-to-noise ratio (HNR). RESULTS The present study replicated previous findings of interprogram differences for healthy speakers, with MDVP consistently yielding higher values than Praat and TF32 for SD F0, jitter, and shimmer and lower values for HNR. Similar, but magnified patterns of results were observed for speakers with dysphonia. CONCLUSION The variation observed across programs calls into question the validity in comparing voice outcomes reported by one AASP to those previously obtained by another, particularly for acoustic signals with aperiodic components that are commonly present in disordered voices. It is advised that waveforms be visually inspected prior to conducting acoustic analysis, and that voice outcomes not be combined or compared across AASPs.

Acoustic and perceptual voice parameters in subclinical and overt primary hypothyroidism. Auris Nasus Larynx 2021; 49:112-116. [PMID: 34615613 DOI: 10.1016/j.anl.2021.09.003] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2021] [Revised: 09/02/2021] [Accepted: 09/18/2021] [Indexed: 12/18/2022]
Abstract
OBJECTIVE Hypothyroidism is a common endocrine disorder affecting various systems of the body. Only a few studies have focused on the effect of primary hypothyroidism on voice with objective parameters, and none of them compared the effect of subclinical and overt hypothyroidism on voice. The aim of the present study is to evaluate and compare the acoustic and perceptual parameters of voice in patients newly diagnosed with subclinical and overt hypothyroidism. METHODS The study included 26 subclinical hypothyroidism, 26 overt hypothyroidism patients and 30 euthyroid control participants. Perceptual evaluation of voice with GRBAS (grade, roughness, breathiness, asthenia, strain) scale, voice handicap index (VHI)-10, and acoustic voice analysis by using Multi-Dimensional Voice Program were performed for all the participants. RESULTS The voice parameters which showed a statistically significant difference between the groups were frequency parameters (Fo; p= 0.003, Fhi; p=0.010, Flo; p= 0.002) and VHI-10 (p= 0.047). A statistically significant decrease in frequency parameters and a statistically significant increase in VHI-10 were found in overt hypothyroidism group comparing with control group (Fo; p= 0.002, Fhi; p=0.009, Flo; p= 0.001 and VHI-10; p= 0.046). Voice parameters in subclinical hypothyroidism group did not show a statistically significant difference comparing with both control and overt hypothyroidism groups. CONCLUSION In the present study, overt hypothyroidism is found to affect frequency parameters and patients' own subjective assessment of voice. Primary hypothyroidism does not seem to have significant effect on voice parameters until thyroxine levels are affected.

Abstract
OBJECTIVES The present study firstly tries to find subgroups of pathological male and female phonation using data from a number of 534 pathological speakers. Secondly, this subgroup classification provides a basis for achieving voice profiles of pathological phonatory quality. METHODS Using complementarily orientated electroglottographic and acoustic parametrization of phonatory quality, sustained vowel productions of 267 male and 267 female speakers were considered. RESULTS In a first step, a clustering technique differentiates three subgroups within each gender on the basis of the EGG- and three subgroups on the basis of the acoustic parameters. In a second step, this subgroup definition allows one to present voice profiles of pathological speakers by combining the parameter means of the electroglottographically determined subgroups with those of the acoustically determined subgroups. CONCLUSIONS The presented voice profiles provide a finer reference basis for the classification of different pathological phonation types as well as for the evaluation of shifts in individual phonatory behavior due to therapy or spontaneous recovery.

Abstract
OBJECTIVE The purpose of our study was to investigate the impact of surgical mask on some vocal parameters such as F0, vocal intensity, jitter, shimmer and harmonics-to-noise ratio in order to understand how surgical mask can affect voice and verbal communication in adults. METHODS The study was carried out on a selected group of 60 healthy subjects. All subjects were trained to voice a vocal sample of a sustained /a/, at a conversational voice intensity for the Maximum Phonation Time (MPT), wearing the surgical mask and then without wearing the surgical mask. Voice samples were recorded directly in Praat. RESULTS There were no statistically significant differences in any acoustic parameter between the masked and unmasked condition. There was a non-significant decrease in vocal intensity in 65% of the subjects while wearing a surgical mask. CONCLUSIONS The statistical comparison carried out between all the acoustic voice parameters observed, extracted wearing and not wearing a surgical mask did not reveal any significant statistical difference. Most of the subjects, after wearing the surgical mask, presented a decrease in vocal intensity measured. Our conclusion was that wearing a mask is likely to induce the unconscious need to increase the vocal effort, resulting over time in a greater risk of developing functional dysphonia. The reduction of intensity can affect also social interaction and speech audibility, especially for individuals with hearing loss.

Abstract
OBJECTIVES We developed a highly accessible acoustic voice analysis system (VArt) using a handheld device running Android operating system. To provide stable and reliable analysis using readily obtainable equipment under unfavorable conditions, we modified the fundamental frequency (F0) extraction algorithm and designed an intuitive user interface representing a new hoarseness index (real-time Ra: Rart), which is a derivative of harmonics-to-noise ratio developed by Kojima and Shoji (Ra2). Since Rart continues to display analysis results in real time, unlike conventional acoustic analysis, it can be used for evaluation such as during phonosurgery and speech therapy. We evaluated the agreement between the earlier version of acoustic voice analysis software (VA) running on a Windows personal computer and VArt running on a handheld device. METHODS F0, Ra2, and Rart were measured in voice samples of sustained vowel phonation /a/ from 10 healthy volunteers and 22 patients with voice disorders using VA running on a Windows personal computer and VArt running on two types of handheld devices in a sound-treated room or in a medical examination room. Intraclass correlation coefficients were calculated for both systems under both conditions. RESULTS All of the comparisons were highly correlated. CONCLUSIONS Measurements obtained using our newly developed VArt were highly consistent with those using VA, indicating high reliability. Moreover, the new system increases the clinical feasibility of acoustic voice analysis.

[PMID: 32962941 DOI: 10.1016/j.jvoice.2020.08.021] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2020] [Revised: 08/13/2020] [Accepted: 08/14/2020] [Indexed: 11/21/2022]
Abstract
OBJECTIVES The aim of the present study was to investigate the validity (both concurrent and diagnostic) and test-retest reliability of Acoustic Voice Quality Index (AVQI) version 2 (AVQI 02.06) in Turkish speaking population. MATERIALS AND METHODS Two hundred and fifty five native Turkish subjects with normal voices (n = 128) and with voice disorders (n = 127) were asked to sustain the vowel [a:] and read aloud the Turkish phonetically balanced text. To determine the test-retest reliability of AVQI, 20 dysphonic (ie, around 15% of the group), and 20 normophonic (ie, around 15% of the group) were reassessed 15 minutes after the first AVQI determination. A three middle seconds of sustained vowel [a:] and a sentence with 25 syllables was concatenated, and AVQI analysis was conducted. The auditory-perceptual evaluation was performed by five experienced raters with Grade (G) from GRBAS Protocol. RESULTS There was a statistically significant correlation between AVQI scores and auditory-perceptual evaluation of overall voice quality (rs = 0.717, P < 0.001). AVQI gave a threshold of 2.98 for the dysphonic voice. The values of intraclass correlation coefficient with two-way mixed-effects model, single-measures type, absolute agreement definition showed an excellent test-retest reliability for AVQI in Turkish language (intraclass correlation coefficient = 0.986). CONCLUSION AVQI v.02.06 is a valid and robust tool in differentiating dysphonic and normal voice, and has excellent test-retest reliability in Turkish language.

Glottal function index questionnaire for screening of pediatric dysphonia. Int J Pediatr Otorhinolaryngol 2019; 123:97-101. [PMID: 31085464 DOI: 10.1016/j.ijporl.2019.04.045] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/04/2019] [Revised: 04/21/2019] [Accepted: 04/30/2019] [Indexed: 11/23/2022]
Abstract
OBJECTIVE to assess the diagnostic value of Lithuanian version of Glottal Function Index (GFI-LT) questionnaire in pediatric dysphonia screening. METHODS The GFI-LT was completed by 82 children (7-16 years old): 41 patients with voice disorders (patients group) and 41 healthy subjects (control group). Auditory-perceptual evaluation of voice was performed using the Grade Roughness Breathiness (GRB) protocol. Acoustic voice analysis was accomplished for F0, SDF0, jitter, shimmer and NNE using Dr. Speech, Tiger Elemetrics software. To evaluate the diagnostic accuracy differentiating normal and dysphonic voice, the receiver operating characteristic statistics were used. RESULTS Perceptually dysphonia was revealed in all children of the patients group. Grade I (65.9%) was the most prevalent (p > 0.05). No dysphonia was detected in the control group. Acoustic voice analysis revealed statistically significantly (p < 0.001) deteriorated all acoustic voice parameters in patients' group comparing to control group. Statistically significant (p < 0.05) strong or moderate correlations were found between the GFI-LT, auditory-perceptual rating and all acoustic voice parameters of the patients group. The strongest correlations were observed between GFI-LT and G (r = 0.70), R (r = 0.69), jitter (r = 0.56) and SDF0 (r = 0.56). No statistically significant correlations between GFI-LT and children' age or gender were found (p > 0.05). The GFI-LT cut-off score of ≥3.0 was associated with excellent test accuracy (AUC = 0.961) distinguishing children with voice disorders from healthy controls, resulting in a balance between sensitivity and specificity (95.1% vs 85.4%). CONCLUSION GFI-LT is considered to be a valid and reliable tool for self-assessment and screening of voice disorders in children.

Evaluation of Voice Quality in Patients With Vocal Fold Polyps: The Size of a Polyp Matters or Does it? J Voice 2019; 34:294-299. [PMID: 31060763 DOI: 10.1016/j.jvoice.2019.04.009] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2019] [Revised: 04/12/2019] [Accepted: 04/16/2019] [Indexed: 11/26/2022]
Abstract
OBJECTIVE This study aimed to investigate the correlation between morphological features of vocal fold polyps (VFPs) and subjective/objective voice parameters. METHODS Perceptual evaluations, aerodynamic and acoustic tests were performed on 47 patients with VFPs. Still images were captured from video and the morphological features associated with the size of VFP were quantified. To reveal the correlation between size-related morphological features (length of polyp base, the ratio of polyp base to vocal fold length, glottal gap area) and objective/subjective parameters of voice, Pearson's and Spearman's tests were carried out. RESULTS This cohort was composed of 30 (63.8 %) male and 17 (36.2%) female patients with the mean age of 45.2 years and 41.3 years, respectively. No correlation was found between the morphological features of VFPs and any of perceptual, aerodynamic and acoustic voice parameters. CONCLUSIONS Our findings indicated that controversies still exist regarding the role of vocal fold polyp morphology in clinical decision making.

The Acoustic Voice Quality Index, Version 03.01, in French and the Voice Handicap Index. J Voice 2018; 34:646.e1-646.e10. [PMID: 30583889 DOI: 10.1016/j.jvoice.2018.11.017] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2018] [Revised: 11/29/2018] [Accepted: 11/30/2018] [Indexed: 11/28/2022]
Abstract
OBJECTIVES The Acoustic Voice Quality Index (AVQI), version 03.01, is a tool for quantitative assessment of the overall severity of dysphonia. Its computation includes six acoustic parameters, which are all analyzed with Praat freeware. It is based on recordings of a sustained vowel and part of a text read aloud. The psychometric qualities of this tool in various languages, including French, have been confirmed by numerous publications. However, studies investigating the correlation between tools for objective vocal assessment and voice-related quality of life show inconsistent results. Hence, the aim of this study was to contribute to the debate on measuring the correlations between the AVQI 03.01 score computed on French samples and the Voice Handicap Index (VHI). METHODS Data from 78 patients were used; they were collected during initial vocal assessment and stored in the ear, nose, and throat caseload database of the University Hospital of Liège. The Spearman rank-order correlations (rs) between the VHI total score and subscores and the AVQI 03.01 scores for French samples were measured. The correlation between the diagnostic decisions ("normophonia" versus "dysphonia") of both tools was assessed using Cramer's phi. RESULTS The Spearman correlation between AVQI 03.01 score and total VHI score, controlling for age, was moderate (rs = 0.62, P < 0.0001). The correlations between the AVQI 03.01 score and the functional, emotional, and physical subscores of the VHI were also moderate (rs = 0.643, 0.543, and 0.514, respectively, P < 0.0001). The correlation between the two instruments' diagnostic decisions ("normophonia" versus "dysphonia") was also moderate (φ = 0.52, P = 0.000). CONCLUSIONS Although AVQI 03.01 scores were moderately correlated with the VHI total score and subscores, they measure two different things. The AVQI 03.01 assesses overall voice quality in terms of acoustic parameters, whereas the VHI assesses the multidetermined impact on the patient's everyday life. Both results should thus be taken into account, as part of a comprehensive vocal assessment.

Acoustic Voice Analysis and Maximum Phonation Time in Relation to Voice Handicap Index Score and Larynx Disease. J Voice 2018; 34:161.e27-161.e35. [PMID: 30093166 DOI: 10.1016/j.jvoice.2018.07.002] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2018] [Revised: 06/29/2018] [Accepted: 07/02/2018] [Indexed: 12/23/2022]
Abstract
OBJECTIVES Patients with voice-related disorders are ideally treated by a multidisciplinary team. Acoustic voice analysis and patient-reported outcome measures are recommended parts of the clinical assessment. The present paper aims at further documenting the importance of acoustic voice analyses, maximum phonation time (MPT) and Voice Handicap Index (VHI) into clinical investigations. STUDY DESIGN The participants (N = 80 larynx cancer, N = 32 recurrent palsy, N = 23 dysfunctional, N = 75 degenerative/inflammation (N = 19 various excluded)) were included consecutively at the outpatient laryngology clinic at Haukeland University Hospital. In addition, a control group of 98 healthy subjects were included. METHOD Voice samples, MPT, and the VHI scores in addition to standard clinical information were obtained. Acoustic analyses were performed from these samples determining level of jitter, shimmer and Noise-to-Harmonic ratio (NHR) as well as analyzing frequency of a prolonged vowel. RESULTS Jitter, shimmer, and NHR scores correlated strongly (r ≈ 0.8; P < 0.001) to each other. By Analysis of Variance analyses, we have determined significant dependence on diagnostic group analyzing all the obtained acoustic scores (all P < 0.001). All patient groups but the dysfunctional group scored to some extent worse than the control group (mostly at P < 0.001). In addition, jitter scores from dysfunction group were lower than recurrent palsy group (P < 0.05) and shimmer scores were lower among dysfunctional than the cancer group (P < 0.05). Regarding NHR the cancer patients scored higher than the degenerative/inflammatory group (P < 0.05). The cancer group scored with longer MPT than the degenerative/inflammatory (P < 0.001) and recurrent palsy groups (P < 0.05). CONCLUSION Among larynx disease patients acoustic and MPT analyses segregated with all determined analyses between patients and control conditions except the dysfunctional group, but also to some extent between various patient groups. VHI scores correlated to jitter, shimmer and NHR scores among cancer and degenerative/inflammatory disease patients. Acoustic analyses potentially add information useful to laryngological patient studies.

Is OperaVOX a clinically useful tool for the assessment of voice in a general ENT clinic? BMC EAR, NOSE, AND THROAT DISORDERS 2017; 17:4. [PMID: 28439206 PMCID: PMC5399865 DOI: 10.1186/s12901-017-0037-9] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/03/2016] [Accepted: 04/05/2017] [Indexed: 01/26/2023]
Abstract
Background Objective acoustic analysis is a key component of multidimensional voice assessment. OperaVOX is an iOS app which has been shown to be comparable to Multi Dimensional Voice Program for most principal measures of vocal function. As a relatively cheap, portable and easily accessible form of acoustic analysis, OperaVOX may be more clinically useful than laboratory-based software in many situations. This study aims to determine whether correlation exists between acoustic measurements obtained using OperaVOX, and perceptual evaluation of voice. Methods Forty-four voices from the multidisciplinary voice clinic were examined. Each voice was assessed blindly by a single experienced voice therapist using the GRBAS scale, and analysed using OperaVOX. The Spearman rank correlation co-efficient was calculated between each element of the GRBAS scale and acoustic measurements obtained by OperaVOX. Results Significant correlations were identified between GRBAS scores and OperaVOX parameters. Grade correlated significantly with jitter (ρ = 0.495, p < 0.05), shimmer (ρ = 0.385, p < 0.05), noise-to-harmonic ratio (NHR; ρ = 0.526, p < 0.05) and maximum phonation time (MPT; ρ = −0.415, p < 0.05). Roughness did not correlate with any of the measured variables. Breathiness correlated significantly with jitter (ρ = 0.342, p < 0.05), NHR (ρ = 0.344, p < 0.05) and MPT (ρ = −0.336, p < 0.05). Aesthenia correlated with NHR (ρ = 0.413, p < 0.05) and MPT (ρ = −0.399, p < 0.05). Strain correlated with Jitter (ρ = 0.560, p < 0.05), NHR (ρ = 0.600, p < 0.05) and MPT (ρ = −0.356, p < 0.05). Conclusions OperaVOX provides objective acoustic analysis which has shown statistically significant correlation to perceptual evaluation using the GRBAS scale. The accessibility of the software package makes it possible for a wide range of health practitioners, e.g. general ENT surgeons, vascular surgeons, thyroid surgeons and cardiothoracic surgeons to objectively monitor outcomes and complications of surgical procedures that may affect vocal function. Given the increasing requirement for surgeons to monitor their outcomes as part of the move towards ‘surgeon reported outcomes’ this may become an invaluable tool towards that goal.

Subjective and Objective Effects of Androgen Ablation Therapy on Voice. J Voice 2015; 29:490-3. [PMID: 25704476 DOI: 10.1016/j.jvoice.2014.09.010] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2014] [Accepted: 09/08/2014] [Indexed: 11/28/2022]
Abstract
OBJECTIVES The aim of present study was to evaluate possible side effects of androgen deprivation therapy (ADT) on voice quality by means of objective and subjective measures. STUDY DESIGN Cross-sectional. METHODS Thirty-five male patients who had been diagnosed with prostate cancer and who had been using bicalutamide and goserelin acetate combination for at least 12 months were included in the study. Thirty healthy nonsmoker males of similar age and without any laryngeal pathology constituted the control group. Acoustic and aerodynamic voice analyses and voice handicap index-10 were applied to both groups. Maximum phonation time, fundamental frequency, jitter, shimmer, and noise-to-harmonic ratio were determined during acoustic and aerodynamic voice analyses. RESULTS Maximum phonation times were 18.86 ± 5.24 and 24.20 ± 3.59 in ADT and control groups, respectively. It was significantly higher in the control group. Fundamental frequencies were 143.73 ± 18.47 and 135.00 ± 13.18 in ADT and control groups, respectively. Jitter values were 2.72 ± 0.62 and 1.99 ± 0.27 in ADT and control groups, respectively. Shimmer values were 11.50 ± 1.81 and 10.48 ± 1.36 in ADT and control groups, respectively. Fundamental frequency, jitter, and shimmer values were significantly higher in the ADT group. Noise-to-harmonic ratio values did not differ between groups. Voice handicap index-10 result was significantly higher in the ADT group. CONCLUSIONS ADT has adverse effects on the human voice. Prospective studies with long-term follow-up of a larger cohort are required for more detailed analysis.

Abstract
PURPOSE The objective of this study was to evaluate the presence of etiologic factors, symptoms, and vocal acoustic alterations related to vocal hyperfunction in children with attention deficit hyperactivity disorder (ADHD). METHOD In 23 children with ADHD and 28 control children, vocal acoustic exploration was performed to analyze the F₀, jitter %, and voice turbulence index for the sustained vowels /a/ and /i/ and the average tone and intensity and tonal modulation in tests of continuous speech. The children's parents completed a specific questionnaire aimed at detecting etiologic factors and vocal symptoms. RESULTS Children with ADHD displayed more vocal symptoms (hoarseness, neck strain, and shortness of breath while talking) and more etiologic factors (they shouted more, spoke louder and faster, and became angry more easily) than did children in the Control group. Likewise, children in the ADHD group exhibited a greater % jitter and a lower average intensity in the continuous speech tests. CONCLUSIONS These results indicate that children with ADHD display greater vocal hyperfunction as compared with children in the Control group and suggest a higher risk of developing dysphonia. The results of this study could be useful for designing vocal programs focusing on vocal education and hygiene to prevent and decrease vocal risks and on promoting vocal health in children with ADHD.

Abstract
To evaluate the change in the voice quality of patients with allergic rhinitis (AR) after medical treatment. The study enrolled 69 subjects: 39 with high serum-specific IgE levels to inhalant allergens as the study group and 30 healthy individuals as controls. All patients were evaluated using the total nasal symptom score (TNSS) and voice handicap index-10 (VHI-10) and then underwent an acoustic voice analysis. After 1 month of treatment with mometasone furoate nasal spray (two 50-μg puffs in each nostril once daily) and desloratadine (5-mg tablet once daily), the patients repeated the surveys and acoustic voice analysis. The results before and after treatment were compared. The TNSS and VHI-10 scores decreased significantly after treatment (p < 0.01). After treatment, the acoustic analysis parameters improved significantly and were similar to the control group, and the maximum phonation time increased significantly (p < 0.05). The voice quality of patients with AR is improved with medical treatment.
