“…The results of acoustic analysis for vowel productions by Mandarin-speaking children with CIs are consistent with those reported for children with CIs using Croatian, German and English in that they all exhibit smaller vowel spaces and more variant F2 patterns compared with children with NH (Liker, Mildner, and Sindija 2007;Neumeyer, Harrington, and Draxler 2010;Turgeon et al 2017). For instance, Liker, Mildner, and Sindija (2007) showed that Croatian-speaking children with CIs have higher F2 values in /i e a o u/ than their NH peers.…”

Objective: This study aimed to systematically review and critically appraise the literature describing the phonetic characteristics and accuracy of the consonants, vowels and tones produced by Mandarin-speaking children with cochlear implants (CIs). Design: The protocol in this review was designed in conformity with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. EBSCOhost, PubMed, Scopus, PsycINFO, ProQuest Central databases were searched for relevant articles which met the inclusion criteria. Study sample: A total of 18 journal papers were included in this review. Results:The results revealed that Mandarin-speaking children with CIs perform consistently more poorly in their production of consonants, in particular on fricatives, have a smaller and less well-defined vowel space, and exhibit greater difficulties in tone realisation, notably T2 and T3, when compared to their normal-hearing (NH) peers. The results from acoustic and accuracy analyses are negatively correlated with CI implantation age, but largely positively correlated with hearing age. Conclusions: Findings of this review highlight the factors that influence consonant, vowel and tone production in Mandarin-speaking children with CIs, thereby providing critical information for clinicians and researchers working with this population.

“…One of the most efficient ways to disambiguate such interpretations is to examine production with and without auditory feedback, i.e., by turning the CI on and off. Such studies differ in their outcome, with some showing differences between the two conditions (Poissant et al, 2006; Bharadwaj et al, 2007) and others finding no difference in the acoustics of their speech (Tye-Murray et al, 1996; Turgeon et al, 2017). Applied to lexical tones, similar designs would be greatly informative.…”

“…Applied to lexical tones, similar designs would be greatly informative. Also critical is the fact that the mechanics of speech production may actually differ (e.g., when the feedback is on or off) even when no acoustic difference is observed in the recordings, which is why articulatory measures may eventually be necessary to fully understand the abnormal vocal production by CI users and their relation to experience-related plasticity (Turgeon et al, 2015, 2017).…”

Purpose: This study examined the utilization of multiple types of acoustic information in lexical tone production and perception by pediatric cochlear implant (CI) recipients who are native speakers of Mandarin Chinese. Methods: Lexical tones were recorded from CI recipients and their peers with normal hearing (NH). Each participant was asked to produce a disyllabic word, yan jing , with which the first syllable was pronounced as Tone 3 (a low dipping tone) while the second syllable was pronounced as Tone 1 (a high level tone, meaning “eyes”) or as Tone 4 (a high falling tone, meaning “eyeglasses”). In addition, a parametric manipulation in fundamental frequency (F0) and duration of Tones 1 and 4 used in a lexical tone recognition task in Peng et al. (2017) was adopted to evaluate the perceptual reliance on each dimension. Results: Mixed-effect analyses of duration, intensity, and F0 cues revealed that NH children focused exclusively on marking distinct F0 contours, while CI participants shortened Tone 4 or prolonged Tone 1 to enhance their contrast. In line with these production strategies, NH children relied primarily on F0 cues to identify the two tones, whereas CI children showed greater reliance on duration cues. Moreover, CI participants who placed greater perceptual weight on duration cues also tended to exhibit smaller changes in their F0 production. Conclusion: Pediatric CI recipients appear to contrast the secondary acoustic dimension (duration) in addition to F0 contours for both lexical tone production and perception. These findings suggest that perception and production strategies of lexical tones are well coupled in this pediatric CI population.

“…Access to speech sounds in the early years of life is mandatory for the optimal development of expressive language and speech. The absence of auditory input over these years can affect irreversible changes in the auditory cortex, as a result of which children with primary hearing impairment may face serious challenges in the perception and articulation of speech, even if they use amplifying devices [2].…”

“…Hearing impairment can affect the perception and hearing of speech sounds and may reduce or distort them and can also affect speech and language skills, articulation accuracy, speech intelligibility, reading and writing, verbal working memory skills and social functions. To this end, specialists should identify limitations in auditory perception caused by auditory defects [2,5,11].…”

Background and ObjectivesA major part of speech perception is based on understanding and distinguishing between vocal cues in the speaker's speech. Consonants and vowels are vocal cues that can be affected by hearing impairment and their perception may thus be reduced or distorted. The present study aims to investigate the auditory perception of consonant contrasts in cochlear implant children. Materials and Methods The present cross-sectional, descriptive-analytical study was conducted on 24 cochlear implant children aged 9-13 selected through convenience sampling from schools and cochlear implant centers. A test of non-word pairs based on a study conducted by Khavar-Ghazlani was carried out to measure contrast in consonants, place of and manner of articulation and voicing. Results The results of the test showed that cochlear implant children scored lower in the perception of voicing compared to the other two features. No significant differences were observed between their perceptions of place of articulation and manner of articulation. Conclusion Cochlear implant children appear to have a poorer perception of voicing contrast compared to the other features, which may be due to the greater reliance of this feature on auditory signs.
