Abstract
Objective: To assess the recognition of lexical tones in Mandarin-speaking bimodal cochlear implant (CI) subjects.Design: Lexical tone recognition in quiet and noise (SNR= +5 dB) was measured with electric stimulation (CI alone) or bimodal stimulation (CI + hearing aid (HA)). The recognition and confusion rates of the four tones (T1, T2, T3 and T4) were analysed. Spearman correlation analysis was performed to examine the relationship between hearing levels in the contralateral ear and bimodal benefits.Study sample: Twenty native Mandarin-speaking bimodal CI users, with ages ranging from 16-49 years.Results: Relative to the CI alone, mean tone recognition with the CI + HA improved significantly from 84.1-92.1% correct in quiet (+8 points) and from 57.9-73.1% correct in noise (+15.2 points). Tone confusions between T2 and T3 were the most prominent in all test conditions, and T4 tended to be labelled as T3 in noise. There was no significant correlation between the bimodal benefits for tone recognition and the unaided or HA-aided pure-tone thresholds at 0.25 kHz.Conclusion: Listeners with CI + HA exhibited significantly better tone recognition than with CI alone. The bimodal advantage for tone recognition was greater in noise than in quiet, perhaps due to a ceiling effect in quiet.

Li N, Wang S, Wang X, Xu L. Contributions of lexical tone to Mandarin sentence recognition in hearing-impaired listeners under noisy conditions. THE JOURNAL OF THE ACOUSTICAL SOCIETY OF AMERICA 2019; 146:EL99. [PMID: 31472569 PMCID: PMC6909998 DOI: 10.1121/1.5120543] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/29/2019] [Revised: 07/11/2019] [Accepted: 07/16/2019] [Indexed: 06/10/2023]
Abstract
Mandarin sentence recognition using natural-tone and flat-tone sentences was tested in 22 subjects with sensorineural hearing loss (SNHL) and 25 listeners with normal hearing (NH) in quiet, speech-shaped noise, and two-talker-babble conditions. While little effects of flat tones on sentence recognition were seen in the NH listeners when the signal-to-noise ratio (SNR) was ≥0 dB, the SNHL listeners showed decreases in flat-tone-sentence recognition in quiet and at +5-dB SNR. Such declined performance was correlated with their degrees of hearing loss. Lexical tone contributes greatly to sentence recognition in hearing-impaired listeners in both quiet and in noise listening conditions.

Abstract
The aim of this study was to investigate hidden hearing loss in patients with Charcot-Marie-Tooth disease type 1 A (CMT1A), a common inherited demyelinating neuropathy. By using pure-tone audiometry, 43 patients with CMT1A and 60 healthy controls with normal sound detection abilities were enrolled. Speech perception in quiet and noisy backgrounds, spectral ripple discrimination (SRD), and temporal modulation detection (TMD) were measured. Although CMT1A patients and healthy controls had similar pure-tone thresholds and speech perception scores in a quiet background, CMT1A patients had significantly (p < 0.05) decreased speech perception ability in a noisy background compared to controls. CMT1A patients showed significantly decreased temporal and spectral resolution (both p < 0.05). Also, auditory temporal processing of CMT1A patients was correlated with speech perception in a noisy background (r = 0.447, p < 0.01) and median motor conduction velocity (r = 0.335, p < 0.05). Therefore, we assumed that demyelination of auditory nerve in CMT1A causes defective cochlear neurotransmission, which reduces temporal resolution and speech perception in a noisy background. Because the temporal resolution test was well correlated with the degree of demyelination in auditory and peripheral motor nerves, temporal resolution testing could be performed as an additional marker for CMT1A.

Hou L, Xu L. Role of short-time acoustic temporal fine structure cues in sentence recognition for normal-hearing listeners. THE JOURNAL OF THE ACOUSTICAL SOCIETY OF AMERICA 2018; 143:EL127.

Abstract
Short-time processing was employed to manipulate the amplitude, bandwidth, and temporal fine structure (TFS) in sentences. Fifty-two native-English-speaking, normal-hearing listeners participated in four sentence-recognition experiments. Results showed that recovered envelope (E) played an important role in speech recognition when the bandwidth was > 1 equivalent rectangular bandwidth. Removing TFS drastically reduced sentence recognition. Preserving TFS greatly improved sentence recognition when amplitude information was available at a rate ≥ 10 Hz (i.e., time segment ≤ 100 ms). Therefore, the short-time TFS facilitates speech perception together with the recovered E and works with the coarse amplitude cues to provide useful information for speech recognition.

Abstract
Amusia is a pitch perception disorder associated with deficits in processing and production of both musical and lexical tones, which previous reports have suggested may be constrained to fine-grained pitch judgements. In the present study speakers of tone-languages, in which lexical tones are used to convey meaning, identified words present in chimera stimuli containing conflicting pitch-cues in the temporal fine-structure and temporal envelope, and which therefore conveyed two distinct utterances. Amusics were found to be more likely than controls to judge the word according to the envelope pitch-cues. This demonstrates that amusia is not associated with fine-grained pitch judgements alone, and is consistent with there being two distinct pitch mechanisms and with amusics having an atypical reliance on a secondary mechanism based upon envelope cues.

Qi B, Mao Y, Liu J, Liu B, Xu L. Relative contributions of acoustic temporal fine structure and envelope cues for lexical tone perception in noise. THE JOURNAL OF THE ACOUSTICAL SOCIETY OF AMERICA 2017; 141:3022.

Abstract
Previous studies have shown that lexical tone perception in quiet relies on the acoustic temporal fine structure (TFS) but not on the envelope (E) cues. The contributions of TFS to speech recognition in noise are under debate. In the present study, Mandarin tone tokens were mixed with speech-shaped noise (SSN) or two-talker babble (TTB) at five signal-to-noise ratios (SNRs; -18 to +6 dB). The TFS and E were then extracted from each of the 30 bands using Hilbert transform. Twenty-five combinations of TFS and E from the sound mixtures of the same tone tokens at various SNRs were created. Twenty normal-hearing, native-Mandarin-speaking listeners participated in the tone-recognition test. Results showed that tone-recognition performance improved as the SNRs in either TFS or E increased. The masking effects on tone perception for the TTB were weaker than those for the SSN. For both types of masker, the perceptual weights of TFS and E in tone perception in noise was nearly equivalent, with E playing a slightly greater role than TFS. Thus, the relative contributions of TFS and E cues to lexical tone perception in noise or in competing-talker maskers differ from those in quiet and those to speech perception of non-tonal languages.

Abstract
OBJECTIVES/HYPOTHESIS The present study aimed to examine whether the response patterns to the chimeric lexical tone tokens, combined with their pure tone audiometry (PTA) results, could separate listeners with sensorineural hearing loss (SNHL) from listeners with auditory neuropathy spectrum disorder (ANSD). STUDY DESIGN Case-control study. METHODS Forty-three SNHL subjects and 46 ANSD subjects participated in a Mandarin lexical tone perception test using original and chimeric tone tokens. Ten sets of monosyllables, with four tone patterns for each, were processed through a 16-channel chimeric synthesizer in which a temporal envelope (E) from a monosyllabic word of one tone was paired with a fine structure (FS) from the same monosyllable of other tones. RESULTS Significantly negative correlations were present between tone perception scores and PTA0.5-4 kHz for both SNHL (P < 0.001) and ANSD (P < 0.001) subjects. Overall, 72.4%, 66.4%, and 46.3% of the tone responses were consistent with FS for the SNHL subjects with mild, moderate, and severe degree of hearing loss, respectively; and 28.4%, 23.1%, and 22.7% were consistent with FS for the ANSD subjects, with the equivalent degree of hearing loss. Similarly, 17.6%, 24.2%, and 37.7% of the tone responses were consistent with E for the SNHL subjects with mild, moderate, and severe degree of hearing loss, respectively; and 45.5%, 44.3%, and 36.5% were consistent with E for the ANSD subjects. CONCLUSION Subjects with SNHL and ANSD may be separated by representing their FS- and E-consistent tone responses as a function of their pure-tone hearing thresholds. LEVEL OF EVIDENCE 3b.
