“…The present case report aimed to analyze and classify the consonant repertoire during the pre-linguistic and first lexical stage of speech development of a child with CI. The present findings agree with those of other studies [15,16], which report that CI consonant repertoire is dominated by labials, alveolars and nasals; however, alveolar plosives outnumber other categories in the present study, in accordance with the "coronal preference" documented in previous literature [17]. As for voicing, voiceless consonants appear twice as often in comparison with voiced consonants.…”

Objective: The present case study aims to report on the consonant repertoire during the pre-linguistic and first linguistic stage of a Greek-Cypriot speaking child bilaterally implanted with multichannel Cochlear Implants (CIs). Background: Children with Hearing Loss (HL) produce canonical babble later, and consonantal inventories of HL children are smaller. However, the consonant repertoire of CI Greek-speaking children has not been examined thus far and research on types of consonantal errors during phonological acquisition is scant. Clinical Case: A pre-linguistically deaf child (CY, 7;0 years old) received the first CI at 7 months of age, but the external part of the device was fitted at 2;7 years. An investigation of the child’s speech at 7;0 years was conducted through auditory analysis. The child’s canonical utterances were transcribed in IPA and his consonants were classified into subcategories, depending on articulation place, articulation manner and resonance. Regarding place, alveolar consonants were the main category produced. As regards manner, closed consonants was the first category to appear, while in terms of voicing, voiceless consonants were recorded more often than voiced ones. The analysis also showed that consonants /t/, /s/ and /p/ were dominant in the child’s speech and revealed several phonological processes. Conclusion: The present case holds special interest as the child’s phonological system is still between the pre-linguistic/first linguistic stages due to the delayed CI mapping. The results agree in part with several studies in the literature, while specific phonological error patterns observed, remain to be verified in other CI Greek-speaking children.

“…These findings are consistent with the majority of studies from other cultural and linguistic settings (e.g. Sundarrajan et al 2019;Sosa and Bunta 2019;Reidy et al 2017). Similar results were found, for instance, in children growing up with English, French or German (Asad et al 2018;Gaul Bouchard et al 2007;Seifert et al 2002).…”

“…Both early implantation age and longer hearing experience have been widely reported as beneficial for children with CIs' development on segmental and suprasegmental features, see e.g. studies on English, Cantonese and Spanish (Connor et al 2006;Dettman et al 2016;Lehnert-LeHouillier et al 2019;Sundarrajan et al 2019 ). The influence of age at implantation is likely related to a sensitive period in children's central auditory development, which has been suggested to occur between 3;6 and 7 years (Sharma, Dorman, and Kral 2005;Sharma, Nash, and Dorman 2009;Schorr et al 2005).…”

“…The decreased neural plasticity in late implanted children may adversely affect their neural organisation for audition and cause poor speech performance (Houston and Miyamoto 2010). The beneficial effect of longer device use experience, in turn, is related to language input and oral-aural communication practice (Sundarrajan et al 2019;Lehnert-LeHouillier et al 2019). For example, Sundarrajan et al (2019) demonstrated that children with CIs with longer device use had better consonant accuracy and a larger consonant inventory.…”

For example, Sundarrajan et al (2019) demonstrated that children with CIs with longer device use had better consonant accuracy and a larger consonant inventory. However, Blamey et al (2001) reported that children with CIs only rapidly develop phones in the first five years post-implantation and then reach a developmental plateau.…”

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.
