Voice And Gender Incongruence: Relationship Between Vocal Self-Perception And Mental Health Of Trans Women

Gender-Affirming Voice Training for Trans Women: Acoustic Outcomes and Their Associations With Listener Perceptions Related to Gender

OBJECTIVES

To investigate acoustic outcomes of gender-affirming voice training for trans women wanting to develop a female sounding voice and to describe what happens acoustically when male sounding voices become more female sounding.

STUDY DESIGN

Prospective treatment study with repeated measures.

METHODS

N = 74 trans women completed a voice training program of 8-12 sessions and had their voices audio recorded twice before and twice after training. Reference data were obtained from N = 40 cisgender speakers. Fundamental frequency (fo), formant frequencies (F1-F4), sound pressure level (Leq), and level difference between first and second harmonic (L1-L2) were extracted from a reading passage and spontaneous speech. N = 79 naive listeners provided gender-related ratings of participants' audio recordings. A linear mixed-effects model was used to estimate average training effects. Individual level analyses determined how changes in acoustic data were related to listeners' ratings.

RESULTS

Group data showed substantial training effects on fo (average, minimum, and maximum) and formant frequencies. Individual data demonstrated that many participants also increased Leq and some increased L1-L2. Measures that most strongly predicted listener ratings of a female sounding voice were: fo, average formant frequency, and Leq.

CONCLUSIONS

This is the largest prospective study reporting on acoustic outcomes of gender-affirming voice training for trans women. We confirm findings from previous smaller scale studies by demonstrating that listener perceptions of male and female sounding voices are related to acoustic voice features, and that voice training for trans women wanting to sound female is associated with desirable acoustic changes, indicating training effectiveness. Although acoustic measures can be a valuable indicator of training effectiveness, particularly from the perspective of clinicians and researchers, we contend that a combination of outcome measures, including client perspectives, are needed to provide comprehensive evaluation of gender-affirming voice training that is relevant for all stakeholders.

Direct Transvestibular Feminization Thyroid Laryngochondroplasty

BACKGROUND

Feminization laryngochondroplasty (FLC) methods have evolved from using a midcervical incision to a submental, less visible incision. The scar may be unacceptable to the patient because it signals gender reassignment surgery. An endoscopic transoral approach to FLC inspired by transoral endoscopic thyroidectomy was recently suggested to avoid the neck scar; however, it requires special equipment and has a long learning curve. A vestibular incision is used to approach the chin in lower-third facial feminization surgery. The authors propose that this incision may be extended to the thyroid cartilage in performing direct FLCs. The authors describe their experience with a novel, minimally invasive, direct transvestibular use of the chin-reshaping incision.

METHODS

The medical records of all patients who underwent direct transvestibular FLC (DTV-FLC) from December of 2019 to September of 2021 were retrieved and reviewed for this retrospective cohort study. Data on the operative, postoperative, and follow-up courses, complications, and functional and cosmetic results were retrieved.

RESULTS

Nine transgender women were included. Seven DTV-FLCs were performed during lower-third facial feminization surgery, and two were isolated DTV-FLCs. One was a revision DTV-FLC. Transient minor complications were encountered and resolved by the postoperative visit at 1 to 2 months. Vocal fold function and voice quality remained intact. Eight available patients were satisfied with the surgical results. A blinded assessment by eight plastic surgeons determined that seven procedures were successful.

CONCLUSION

The novel DTV-FTLC approach either in isolation or as part of lower-third facial feminization surgery facilitated scar-free FLC with satisfactory cosmetic and functional results.

Gender-Affirming Voice Training for Trans Women: Effectiveness of Training on Patient-Reported Outcomes and Listener Perceptions of Voice

PURPOSE

Although speech-language pathologists have provided gender-affirming voice training for trans women since the 1970s, evidence for this training's effectiveness remains weak. Our study aimed to redress limitations of earlier studies and evaluate voice training effects on outcomes important to trans women.

METHOD

Seventy-four trans women (19-54 years old) who wanted a more female-sounding voice were recruited through two health facilities and provided with an eight- to 12-session voice training program based on contemporary literature, usual clinical practice, and client-centered care principles. Self-reported outcomes and an audio-recorded reading sample were collected 3 months before, immediately before and after, and 3 months after training. Forty cisgender speakers were audio-recorded reading the same sample material as comparison voices. Seventy-nine naive listeners made gender-related voice ratings of an extract from these audio recordings. Training effectiveness was evaluated using group-level analyses (linear mixed-effects models) and individual-level analyses to establish what proportion of participants improved to a predetermined relevant degree.

RESULTS

Group-level analyses demonstrated positive training effects, maintained 3 months posttraining, for trans women's vocal satisfaction, perceptions of voice-related social participation, and self- and listener perceptions of their voices. Individual-level analyses also demonstrated positive effects. Two thirds of trans women increased vocal satisfaction to a relevant degree, one third who reported restricted social participation before training reduced this restriction to a relevant degree, and all were rated more female-sounding after training (although not all to a relevant degree).

CONCLUSIONS

All trans women participants made progress toward their voice goals and maintained those gains at follow-up. These findings provide evidence that gender-affirming speech-language pathology services warrant prioritization. Further research is warranted to investigate factors predicting outcomes of voice training for trans women.

Spectral analysis of strident fricatives in cisgender and transfeminine speakersa)

The spectral features of /s/ and /ʃ/ carry important sociophonetic information regarding a speaker's gender. Often, gender is misclassified as a binary of male or female, but this excludes people who may identify as transgender or nonbinary. In this study, we use a more expansive definition of gender to investigate the acoustics (duration and spectral moments) of /s/ and /ʃ/ across cisgender men, cisgender women, and transfeminine speakers in voiced and whispered speech and the relationship between spectral measures and transfeminine gender expression. We examined /s/ and /ʃ/ productions in words from 35 speakers (11 cisgender men, 17 cisgender women, 7 transfeminine speakers) and 34 speakers (11 cisgender men, 15 cisgender women, 8 transfeminine speakers), respectively. In general, /s/ and /ʃ/ center of gravity was highest in productions by cisgender women, followed by transfeminine speakers, and then cisgender men speakers. There were no other gender-related differences. Within transfeminine speakers, /s/ and /ʃ/ center of gravity and skewness were not related to the time proportion expressing their feminine spectrum gender or their Trans Women Voice Questionnaire scores. Taken together, the acoustics of /s/ and /ʃ/ may signal gender group identification but may not account for within-gender variation in transfeminine gender expression.

Factors Associated With Loss of Follow-Up in Transgender Patients Receiving Vocal Therapy

OBJECTIVES

Optimal vocal care for transgender patients necessitates regular follow-up. Factors associated with loss of follow-up in voice patients have never been investigated. In this study, we report a case series of transgender patients seeking vocal care at our institution and compare those who were and were not lost to follow-up.

METHODS

Charts of transgender patients diagnosed with gender dysphoria who sought vocal care at our institution from January 2018 through May 2022 were reviewed. A chronological timeline of each patient's care at our vocal clinic was recorded. Loss of follow-up was defined as instances in which patients were not yet satisfied with their vocal outcomes and expressed interest in scheduling a subsequent visit but had not yet done so. Logistic regressions were performed to identify factors associated with loss of follow-up.

RESULTS

Of 73 patients identified, 59 (80.8%) were assigned male at birth, and 72 (98.6%) were non-Hispanic White. Loss of follow-up occurred in 35 (47.9%) patients. Patients who received vocal surgery were significantly less likely to be lost to follow-up (OR: 0.16 (0.03, 0.79); p = 0.03). The availability of telemedicine options for vocal care was protective against loss of follow-up (OR: 0.09 (0.02, 0.44); p = 0.003). Patients who received other non-voice gender-affirming treatments concomitant to their vocal care were more likely to be lost to follow-up (OR: 4.44 (1.35, 14.59); p = 0.01).

CONCLUSION

Loss of follow-up in transgender patients receiving vocal care is common. Providing telemedicine options and encouraging patients to complete vocal care prior to or after receiving other non-voice gender-affirming treatments may help increase rates of follow-up.

Needs Assessment of Gender-Affirming Face, Neck, and Voice Procedures and the Role of Gender Dysphoria

OBJECTIVE

To assess the needs of transgender and nonbinary (TNB) adults for gender-affirming face, neck, and voice procedures.

STUDY DESIGN

Cross-sectional survey.

SETTING

Online, February to May 2022.

METHODS

Primary outcomes included utilization of otolaryngologists and speech-language pathologists; gender dysphoria felt from the face, neck, and voice self-reported on a 0 to 10 numeric rating scale (0 = no dysphoria, 10 = unbearable); and desire for various gender-affirming face, neck, and voice procedures. We used ordinal logistic and linear regression to assess relationships between site-specific dysphoria and the desire for relevant procedures.

RESULTS

TNB participants (N = 234) infrequently sought gender-affirming care with speech-language pathologists (23%), facial plastic surgeons (8%), or laryngologists (3%). Participants experienced the strongest dysphoria from the voice (median 7/10), jawline/chin (4/10), and neck (3.5/10). Transmasculine and nonbinary participants typically seeking masculinization (n = 83) frequently desired voice therapy (want = 35%, had = 8%). Transfeminine and nonbinary participants typically seeking feminization (n = 145) frequently desired voice therapy (want = 52%, had = 23%), chondrolaryngoplasty (want = 45%, had = 5%), and hair removal/electrolysis (want = 43%, had = 44%). Many desired at least 1 facial feminization surgery procedure (65%), especially mandible reduction (want = 42%, had = 3%), rhinoplasty (want = 41%, had = 1%), and forehead reduction (want = 37%, had = 4%). Dysphoria ratings were associated with desiring relevant procedures (p < .05 for all), notably voice therapy (odds ratio [OR] = 1.50), chondrolaryngoplasty (OR = 1.46), mandible reduction (OR = 1.38), rhinoplasty (OR = 1.59), and forehead reduction (OR = 1.82).

CONCLUSION

Gender dysphoria from the face, neck, and voice can be severe for TNB people and is associated with the desire for gender-affirming procedures. The high demand yet low reported access to these procedures highlights the need for providers of gender-affirming face, neck, and voice care.

Characterizing Gender-Affirming Voice Intervention Discussion on Social Media: A Cross-Platform Analysis

OBJECTIVES

Gender-affirming voice treatments, such as voice training and surgery, are highly impactful for transgender patients experiencing vocal dysphoria and may be discussed on social media platforms including Twitter and Reddit. Our goal was to characterize the content and sentiment of social media posts pertaining to gender-affirming voice interventions to better understand the needs of this patient population.

STUDY DESIGN

Retrospective data-mining study.

METHODS

A total of 18,695 Tweets from 2001 to 2021 and 23,742 r/Transvoice Reddit submissions and comments from 2009 to 2020 were extracted via publicly available application programming interfaces and analyzed using language processing and sentiment analysis techniques. One thousand eighty-six highly emotive r/Transvoice posts related to voice modification treatments were manually reviewed for further classification.

RESULTS

Online discussion of gender-affirming voice has increased over time and is centered on vocal feminization. Recurrent themes included use of online training resources, singing voice, and barriers to care such as cost and variable experiences with health care providers. Sentiment analysis demonstrated that posts discussing gender-affirming voice training had higher average sentiment scores than those discussing voice surgery, on both Twitter (0.252 vs 0.161; P < 0.001) and Reddit (0.349 vs 0.301; P < 0.001). Frequently appearing themes in highly negative surgery posts included mixed outcomes (9.3%), surgical complications (9.3%), and recovery time (8.5%). Common themes shared by the positive subgroup analysis included peer support, vocal quality, and importance of practice.

CONCLUSIONS

Gender-diverse patients share various concerns and resources relating to voice intervention in the online communities of Twitter and Reddit. The discussion has been growing over the past decade and is mostly positive, with significant social support and resource-sharing within the community. Aggregated online sentiment toward gender-affirming voice surgery is more negative than voice training, largely due to concerns about surgical outcomes and variability, risks, and recovery period.

Gender-Affirming Voice Modification for Transgender Women: Characteristics and Outcomes

Objective

The primary aim of this study was to define characteristics of transgender women seeking gender-affirming voice modification at our voice center. The secondary aim was to evaluate outcome measures, comparing (a) behavioral voice training alone, (b) surgery alone, and (c) combination of behavioral voice training+surgery.

Methods

Patients seen in a 30-month period, who sought care for gender-affirming voice modification, were included if they were assigned male at birth and identified as female. Patient demographic information, patient quality of life index scores, Trans Woman Voice Questionnaire (TWVQ), and acoustic data were collected before and after intervention.

Results

Sixteen patients met inclusion criteria. The majority of patients were (a) undergoing hormone replacement therapy at initiation of treatment, (b) were presenting in public for over 2 years as female, and (c) had a history of psychological disorders (i.e., gender dysphoria, anxiety, depression, and attention deficit hyperactivity disorder [ADHD]). Increased f0 and decreased TWVQ scores were evident and statistically significant within behavioral voice training cohort and behavioral voice training+surgery cohort. Treatment groups appear similar with respect to average changes; pre- and post-data were not available for surgery only patients. Greater change in f0 was directly correlated with increased number of voice training sessions.

Conclusion

There is variability in treatment course for patients seeking gender-affirming voice modification; however, treatment type may not impact outcomes. Increased patient quality of life and increased speaking fundamental frequency were found in this patient cohort.

Modification of Wendler Glottoplasty for Male to Female Gender Transition

INTRODUCTION

Transgenderism is a condition regarding the gender identity of an individual where their psychological gender is discordant with their anatomic gender. For patients transitioning from Male to Female, voice changes are created predominantly with voice therapy, with vocal surgery as an adjunct if the patient desires it. A common surgical technique is the Wendler Glottoplasty. A CO₂ laser is used to de-epithelialize the anterior third of the vocal folds and the anterior one-third of the folds are sutured together. This shortens the vibratory folds and increases the fundamental frequency (F₀) of the voice. We present a novel modification that incorporates use of injectable aqueous carboxy-methyl-cellulose gel (Prolaryn) to medialize the anterior aspect of the vocal folds and apply fibrin glue sealant (Tisseal) in lieu of sutures, simplifying the operative technique and a thyroarytenoid myectomy for debulking of the cords in select cases.

METHOD

We present ten patients treated with our modified Wendler Glottoplasty technique. Voice assessment was based on F₀ and frequency range pre and post-operatively measured via MDVP and Real-Time Pitch on the Computerized Speech Lab.

RESULTS

The 10 patients had an average age of 34.0 years (range 22.2-64.3 years). The average preoperative F₀ was 136.1 Hz, with an average frequency range of 108.3-282.4 Hz. Postoperatively, the average F₀ was 245.9 Hz, with an average frequency range of 197.3-300.7 Hz. This led to an average F₀ increase of 106.3 Hz.

CONCLUSION

Our modification to the Wendler Glottoplasty successfully resulted in a significant increase in the postoperative F₀. In addition, there was improved satisfaction in vocal character after the procedure, compared to their preoperative vocal character.

Visual biases in evaluation of speakers' and singers' voice type by cis and trans listeners

Introduction

A singer's or speaker's Fach (voice type) should be appraised based on acoustic cues characterizing their voice. Instead, in practice, it is often influenced by the individual's physical appearance. This is especially distressful for transgender people who may be excluded from formal singing because of perceived mismatch between their voice and appearance. To eventually break down these visual biases, we need a better understanding of the conditions under which they occur. Specifically, we hypothesized that trans listeners (not actors) would be better able to resist such biases, relative to cis listeners, precisely because they would be more aware of appearance-voice dissociations.

Methods

In an online study, 85 cisgender and 81 transgender participants were presented with 18 different actors singing or speaking short sentences. These actors covered six voice categories from high/bright (traditionally feminine) to low/dark (traditionally masculine) voices: namely soprano, mezzo-soprano (referred to henceforth as mezzo), contralto (referred to henceforth as alto), tenor, baritone, and bass. Every participant provided voice type ratings for (1) Audio-only (A) stimuli to get an unbiased estimate of a given actor's voice type, (2) Video-only (V) stimuli to get an estimate of the strength of the bias itself, and (3) combined Audio-Visual (AV) stimuli to see how much visual cues would affect the evaluation of the audio.

Results

Results demonstrated that visual biases are not subtle and hold across the entire scale, shifting voice appraisal by about a third of the distance between adjacent voice types (for example, a third of the bass-to-baritone distance). This shift was 30% smaller for trans than for cis listeners, confirming our main hypothesis. This pattern was largely similar whether actors sung or spoke, though singing overall led to more feminine/high/bright ratings.

Conclusion

This study is one of the first demonstrations that transgender listeners are in fact better judges of a singer's or speaker's voice type because they are better able to separate the actors' voice from their appearance, a finding that opens exciting avenues to fight more generally against implicit (or sometimes explicit) biases in voice appraisal.
