“…Considering the complex characteristics in pitch and durational patterns, early implantation and sufficient CI experience are recommended to facilitate the acquisition and production of Mandarin by children with CIs [Zhou et al, 2013;Tang et al, 2021]. However, a related study only examined the effect of unilateral CI or bimodal stimulation in this population [Gao et al, 2021], and only one study reported the development of early auditory skills in 19 children with simultaneous bilateral CIs [Long et al, 2018]. To our knowledge, this is the first study to investigate the benefit of sequential bilateral cochlear implantation in children speaking Mandarin.…”

Introduction: Cochlear implantation is an effective treatment for children with deafness. Although the binaural effect of bilateral cochlear implantation on sound localization and speech perception in noisy environments has been demonstrated, the outcome and performance predictors of the second cochlear implant (CI2) remain uncertain for patients receiving sequential implantation. This study evaluated the hearing performance between the first cochlear implant (CI1), CI2, and bilateral cochlear implants (CI1+2) among children with sequential bilateral cochlear implantation. Methods: This single-center retrospective study enrolled 14 children and adolescents aged 8–18 years who underwent sequential bilateral cochlear implantation with a mean interimplant interval of 8.2 years. The Mandarin Lexical Neighborhood Test (M-LNT), the Mandarin Hearing in Noise Test (M-HINT), and the Comprehensive Cochlear Implant Questionnaire (CCIQ) scores of participants were evaluated. Mann-Whitney U tests and Spearman correlation analysis were performed to analyze factors associated with CI2 performance. Results: In the 1-year follow-up period after CI2 implantation, although the M-LNT mean score for CI2 was significantly lower than that for CI1, the M-LNT scores for CI2 and CI1+2 improved significantly over time. In a noisy environment, CI1+2 significantly outperformed CI1 in the M-HINT. The M-LNT score for CI2 was significantly associated with preoperative bimodal fitting, residual hearing of the second implanted ear, and CI2 daily-usage time. Specific to CI2, the CCIQ showed improvement 1 year after CI2 implantation. Conclusion: CI2 improved the hearing performance and quality of life of recipients with longer interimplant intervals, especially in noisy environments, and its efficacy was associated with preoperative bimodal fitting and regular daily use.

Background: One of the greatest difficulties of the hearing impaired is understanding speech, especially in the presence of competitive noise. Speech perception issues are a common difficulty for those who have hearing loss. Poor speech perception is the most frequent cause of seeking hearing treatment. The most extensively used treatment to enhance speech perception is hearing aids or other assistive devices. Aim: To evaluate the effect of hearing aid methods on the speech perception of patients with hearing loss. Methods: We conducted our study based on PRISMA recommendations and guidelines. We searched Cochrane, PubMed, Scopus, and Web of Science for relevant clinical trials and prospective observational studies. Clinical trials were assessed according to Cochrane’s risk of bias tool, while observational studies were evaluated according to the National Heart, Lung, and Blood Institute. We involved the following outcomes: speech recognition thresholds, word recognition score (WRS) in noise, and WRS in quiet. Results: Six studies met the eligibility criteria for our meta-analysis. We found that hearing aids can cause an increase in WRS in noise (mean difference [MD]=18.32 [3.08, 33.55], p=0.02) and WRS in quiet (MD=45.13 [7.79, 82.46], p=0.02). In addition, hearing aids lead to a decrease in speech recognition thresholds (MD=45.13 [7.79, 82.46], p=0.02). Conclusions: Hearing aids are an effective treatment for patients with hearing loss. They can significantly improve speech perception (WRS) in quiet and noisy environments and provide other benefits, such as improved communication, increased safety, and better cognitive function. If you or someone you know has hearing loss, it is essential to speak with a healthcare professional about the benefits of using hearing aids.

“…A body of studies evaluated lexical tone performance in Mandarin-speaking CI users, which consistently demonstrated remarkable deficits in their tonal perception and production (Tan et al 2016; Chen & Wong 2017; Gao et al 2021 for reviews). It is noticeable that recognition of naturally spoken Mandarin tones in quiet can be relatively robust in CI users, with an average accuracy of above 75% (Peng et al 2004; Tao et al 2015; Zhang et al 2020a), possibly due to the available duration and intensity cues that co-vary with F0 contour.…”

“…It is a fundamental mechanism underlying the phonetic categorization, which is strongly influenced by listener’s native language experience and auditory deprivation (Harnad 2003; Goldstone & Hendrickson 2010; Zhang 2016 for reviews). Encumbered by auditory deprivations in early life and CI device-related limitations in pitch encoding, kindergarteners with CIs encounter consistent difficultly in lexical tone development that waits for promotion via efficacious interventions (Tan et al 2016; Gao et al 2021 for reviews). In a nutshell, the classical CP paradigm provides an ideal stringent test for the pediatric CI users to assess the training-induced benefits on pitch perception of Mandarin tones in terms of generalizability and sustainability.…”

Objectives: Although pitch reception poses a great challenge for individuals with cochlear implants (CIs), formal auditory training (e.g., high variability phonetic training [HVPT]) has been shown to provide direct benefits in pitch-related perceptual performances such as lexical tone recognition for CI users. As lexical tones in spoken language are expressed with a multitude of distinct spectral, temporal, and intensity cues, it is important to determine the sources of training benefits for CI users. The purpose of the present study was to conduct a rigorous fine-scale evaluation with the categorical perception (CP) paradigm to control the acoustic parameters and test the efficacy and sustainability of HVPT for Mandarin-speaking pediatric CI recipients. The main hypothesis was that HVPT-induced perceptual learning would greatly enhance CI users’ ability to extract the primary pitch contours from spoken words for lexical tone identification and discrimination. Furthermore, individual differences in immediate and long-term gains from training would likely be attributable to baseline performance and duration of CI use. Design: Twenty-eight prelingually deaf Mandarin-speaking kindergarteners with CIs were tested. Half of them received five sessions of HVPT within a period of 3 weeks. The other half served as control who did not receive the formal training. Two classical CP tasks on a tonal continuum from Mandarin tone 1 (high-flat in pitch) to tone 2 (mid-rising in pitch) with fixed acoustic features of duration and intensity were administered before (pretest), immediately after (posttest), and 10 weeks posttraining termination (follow-up test). Participants were instructed to either label a speech stimulus along the continuum (i.e., identification task) or determine whether a pair of stimuli separated by zero or two steps from the continuum was the same or different (i.e., discrimination task). Identification function measures (i.e., boundary position and boundary width) and discrimination function scores (i.e., between-category score, within-category score, and peakedness score) were assessed for each child participant across the three test sessions. Results: Linear mixed-effects (LME) models showed significant training-induced enhancement in lexical tone categorization with significantly narrower boundary width and better between-category discrimination in the immediate posttest over pretest for the trainees. Furthermore, training-induced gains were reliably retained in the follow-up test 10 weeks after training. By contrast, no significant changes were found in the control group across sessions. Regression analysis confirmed that baseline performance (i.e., boundary width in the pretest session) and duration of CI use were significant predictors for the magnitude of training-induced benefits. Conclusions: The stringent CP tests with synthesized stimuli that excluded acoustic cues other than the pitch contour and were never used in training showed strong evidence for the efficacy of HVPT in yielding immediate and sustained improvement in lexical tone categorization for Mandarin-speaking children with CIs. The training results and individual differences have remarkable implications for developing personalized computer-based short-term HVPT protocols that may have sustainable long-term benefits for aural rehabilitation in this clinical population.
