“…As for specific speech patterns produced by young bilingual CI users, studies indicate that bilingual children who use CIs can match the productions of their bilingual peers with NH, such as in voice onset time and prevoicing in each language in word-initial position (Bunta, Goodin-Mayeda, Procter, & Hernandez, 2016). There are, however, unique patterns in the productions of bilingual and monolingual CI users that are reflected in differential productions of postalveolar fricatives and affricates showing effects of both bilingual versus monolingual status and CI use versus NH (Li, Bunta, & Tomblin, 2017). Li et al investigated frication duration, frication rise time, and centroid frequency as acoustic cues in production in monolingual and bilingual CI users and their peers with NH.…”

This study investigates consonant and vowel accuracy and whole-word variability (also called token-totoken variability or token-to-token inconsistency) in bilingual Spanish-English and monolingual English-speaking children with cochlear implants (CIs) compared to their bilingual and monolingual peers with normal hearing (NH). Method: Participants were 40 children between 4;6 and 7;11 (years;months; M age = 6;2), n = 10 each in 4 participant groups: bilingual Spanish-English with CIs, monolingual English with CIs, bilingual Spanish-English with NH, and monolingual English with NH. Spanish and English word lists consisting of 20 words of varying length were generated, and 3 productions of each word were analyzed for percent consonants correct, percent vowels correct, and the presence of any consonant and/or vowel variability. Results: Children with CIs demonstrated lower accuracy and more whole-word variability than their peers with NH. There were no differences in rates of accuracy or whole-word variability between bilingual and monolingual children matched on hearing status, and bilingual children had lower accuracy and greater whole-word variability in English than in Spanish. Conclusions: High rates of whole-word variability are prevalent in the speech of children with CIs even after many years of CI experience, and bilingual language exposure does not appear to negatively impact phonological development in children with CIs. Contributions to our understanding of underlying sources of speech production variability and clinical implications are discussed.

“…Studies with slightly older children (5-6 years of age) show a more nuanced pattern regarding speech production in children with HL, specifically those with CIs. In general, these studies suggest that children with CIs are able to produce voicing distinctions in stop consonants, as well as their peers with NH (Bunta, Goodin-Mayeda, Procter, & Hernandez, 2016), but fail to demonstrate appropriate spectral structure, specifically in voiceless sibilants (Li, Bunta, & Tomblin, 2017). These findings suggest that children with CIs may have access to veridical temporal structure in the acoustic speech signal, but access only to degraded spectral structure.…”

“…Tense vowels were included so that formant frequencies could readily be compared in the vocoded and unprocessed conditions; these vowels are preferable to lax vowels, which tend to have less stable formant patterns. Thus, segments were included that readily supported the analyses of temporal and spectral properties, as other investigators have done (Bunta et al, 2016;Li et al, 2017). Nonwords were used as stimuli, because the imitation of real words might be based more on stored representations than on immediate input.…”

Purpose Child phonologists have long been interested in how tightly speech input constrains the speech production capacities of young children, and the question acquires clinical significance when children with hearing loss are considered. Children with sensorineural hearing loss often show differences in the spectral and temporal structures of their speech production, compared to children with normal hearing. The current study was designed to investigate the extent to which this problem can be explained by signal degradation. Method Ten 5-year-olds with normal hearing were recorded imitating 120 three-syllable nonwords presented in unprocessed form and as noise-vocoded signals. Target segments consisted of fricatives, stops, and vowels. Several measures were made: 2 duration measures (voice onset time and fricative length) and 4 spectral measures involving 2 segments (1st and 3rd moments of fricatives and 1st and 2nd formant frequencies for the point vowels). Results All spectral measures were affected by signal degradation, with vowel production showing the largest effects. Although a change in voice onset time was observed with vocoded signals for /d/, voicing category was not affected. Fricative duration remained constant. Conclusions Results support the hypothesis that quality of the input signal constrains the speech production capacities of young children. Consequently, it can be concluded that the production problems of children with hearing loss—including those with cochlear implants—can be explained to some extent by the degradation in the signal they hear. However, experience with both speech perception and production likely plays a role as well.

“…Moreover, the evidence in other target languages indicates that participants with CIs with longer speech support have better speech performance (Geers 2002;Bunta et al 2016). With respect to the factor of language environment, as well as Li, Bunta, and Tomblin (2017), for instance, showed that English-Spanish bilingual children with CIs have a different pattern in their phonological development than monolingual children with CIs. Moreover, bimodal device use has been reported as beneficial for children with CIs' speech development in both quiet and noisy environments (Cuda et al 2019;Yang and Zeng 2017).…”

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.
