Discrimination of consonants in quiet and in noise in Mandarin-speaking children with normal hearing.

Objective: Given the critical role of consonants in speech perception and the lack of knowledge on consonant perception in noise in Mandarin-speaking children, the current study aimed to investigate Mandarin consonant discrimination in normal-hearing children, in relation to the effects of age and signal-to-noise ratios (S/N).

Design: A discrimination task consisting of 33 minimal pairs in monosyllabic words was designed to explore the development of consonant discrimination in five test conditions: 0, -5, -10, -15 dB S/Ns, and quiet.

Study Sample: Forty Mandarin-speaking, normal-hearing children aged from 4;0 to 8;9 in one-year-age increment were recruited and their performance was compared to 10 adult listeners.

Pre-attentive fundamental frequency processing in Mandarin-speaking children with cochlear implants as revealed by the peak latency of positive mismatch response.

Introduction: Fundamental frequency (F0) serves as the primary acoustic cue for Mandarin tone perception. Recent behavioral studies suggest that F0 information may be differently processed between Mandarin-speaking normal-hearing (NH) children and children with cochlear implants (CIs), which may partially explain the unsatisfactory outcome of lexical tone recognition using CIs with tonal language-oriented speech processing strategies. The aim of the current study was to provide neural evidence of F0 processing in Mandarin-speaking kindergarten-aged children with CIs compared with NH children.

Development and evaluation of the Cantonese matrix sentence test.

Objective: To develop the Cantonese matrix (YUEmatrix) test according to the international standard procedure and examine possible different outcomes in another tonal language.

Design: A 50-word Cantonese base-matrix was established. Word-specific speech recognition functions, speech recognition thresholds (SRT), and slopes were obtained.

Barriers to hearing aid adoption among older adults in mainland China.

Objective: This study aimed to explore barriers to hearing aid adoption amongst older adults in mainland China.

Design: Semi-structured interviews were audio-recorded and analysed using qualitative thematic analysis.

Study Sample: The study included 12 older adults who had seen ENTs and had not adopted hearing aids.

Just-Noticeable Differences of Fundamental Frequency Change in Mandarin-Speaking Children with Cochlear Implants.

Fundamental frequency (F0) provides the primary acoustic cue for lexical tone perception in tonal languages but remains poorly represented in cochlear implant (CI) systems. Currently, there is still a lack of understanding of sensitivity to F0 change in CI users who speak tonal languages. In the present study, just-noticeable differences (JNDs) of F0 contour and F0 level changes in Mandarin-speaking children with CIs were measured and compared with those in their age-matched normal-hearing (NH) peers.

Speech Perception in Noise Is Associated With Different Cognitive Abilities in Chinese-Speaking Older Adults With and Without Hearing Aids.

Chinese-speaking older adults usually do not perceive a hearing problem until audiometric thresholds exceed 45 dB HL, and the audiometric thresholds of the average hearing-aid (HA) user often exceed 60 dB HL. The purpose of this study was to examine the relationships between cognitive and hearing functions (measured as audiometric or speech reception thresholds) in older Chinese adults with HAs and with untreated hearing loss (HL). Participants were 49 Chinese older adults who used HAs and had moderate to severe HL (HA group), and 46 older Chinese who had mild to moderately severe HL but did not use HAs (untreated; or UT group).

A Review of Speech Perception of Mandarin-Speaking Children With Cochlear Implantation.

This paper reviewed the literature on the development of and factors affecting speech perception of Mandarin-speaking children with cochlear implantation (CI). We also summarized speech outcome measures in standard Mandarin for evaluating auditory and speech perception of children with CI. A comprehensive search of Google Scholar and PubMed was conducted from March to June 2021.

Can Dual Compression Offer Better Mandarin Speech Intelligibility and Sound Quality Than Fast-Acting Compression?

The aim of this study was to evaluate the efficacy of dual compression for Mandarin-speaking hearing aid users. Dual compression combines fast and slow compressors operating simultaneously across all frequency channels. The study participants were 31 hearing aid users with symmetrical moderate-to-severe hearing loss, with a mean age of 67 years.

Effects of Fundamental Frequency Contours on Sentence Recognition in Mandarin-Speaking Children With Cochlear Implants.

Purpose Fundamental frequency (F0) is the primary acoustic cue for lexical tone perception in tonal languages but is processed in a limited way in cochlear implant (CI) systems. The aim of this study was to evaluate the importance of F0 contours in sentence recognition in Mandarin-speaking children with CIs and find out whether it is similar to/different from that in age-matched normal-hearing (NH) peers. Method Age-appropriate sentences, with F0 contours manipulated to be either natural or flattened, were randomly presented to preschool children with CIs and their age-matched peers with NH under three test conditions: in quiet, in white noise, and with competing sentences at 0 dB signal-to-noise ratio.

Natural Language Input: Maternal Education, Socioeconomic Deprivation, and Language Outcomes in Typically Developing Children.

Purpose The current study was designed to investigate the differences in language input related to family factors (maternal level of education [MLE] and socioeconomic level of deprivation [SLD]) and their association with language outcomes in preschoolers. Method This study used New Zealand SLD and MLE classification systems to examine differences in language input related to these factors among 20 typically developing preschool children aged 2-5 years. The quantity of children's language input (adult words [AWs], conversational turns [CTs]) was calculated using the Language ENvironment Analysis audiotaping technology for two typical weekend days.

Visual mismatch negativity elicited by semantic violations in visual words.

The remarkable rapidity and effortlessness of speech perception and word reading by skilled listeners or readers suggest implicit or automatic mechanisms underlying language processing. In speech perception, the implicit mechanisms are reflected by the auditory mismatch negativity (MMN) response, suggesting that phonemic, lexical, semantic, and syntactic information are automatically and rapidly processed in the absence of focused attention. In visual word reading, implicit orthographic and lexical processing are reflected by visual mismatch negativity (vMMN), the visual counterpart of auditory MMN.

Development of the mandarin hearing in noise test for children.

To develop a Mandarin version of the Hearing in Noise Test for Children (MHINT-C) and examine the maturational effects on sentence recognition. Sentences suitable for evaluating children aged 6-18 years were selected from the adult MHINT to form 12 lists of 10 MHINT-C sentences (Study 1). List equivalence, inter-list reliability, response variability, and maturational effects on sentence recognition were examined using the MHINT-C (Study 2).

Participants were recruited from the Hearing House, the Speech Clinic at the University of Auckland, and Early Childcare Centers (ECC) in Auckland, New Zealand.

Analysis of Amount and Style of Oral Interaction Related to Language Outcomes in Children With Hearing Loss: A Systematic Review (2006-2016).

Purpose This systematic review summarizes the evidence for differences in the amount of language input between children with and without hearing loss (HL). Of interest to this review is evaluating the associations between language input and language outcomes (receptive and expressive) in children with HL in order to enhance insight regarding what oral language input is associated with good communication outcomes. Method A systematic review was conducted using keywords in 3 electronic databases: Scopus, PubMed, and Google Scholar.

The Role of Lexical Tone Information in the Recognition of Mandarin Sentences in Listeners With Hearing Aids.

Objectives: Lexical tone information provides redundant cues for the recognition of Mandarin sentences in listeners with normal hearing in quiet conditions. The contribution of lexical tones to Mandarin sentence recognition in listeners with hearing aids (HAs) is unclear. This study aimed to remove lexical tone information and examine the effects on Mandarin sentence intelligibility in HA users.
