“…Por outro lado, também é importante ressaltar que os participantes utilizaram dispositivos tecnológicos de acesso aos sons da fala e participaram de programa de reabilitação auditiva, possibilitando que aqueles com maiores escores de PCC e de PCC-r atingissem grau de inteligibilidade de fala "Boa". Esses achados concordam com pesquisas que destacam o impacto desses fatores na produção de fala (6,24,25) .…”

RESUMO Objetivo caracterizar a produção da fala de crianças e adolescentes usuários de aparelho de amplificação sonora individual (AASI) ou implante coclear (IC) de um programa de reabilitação auditiva. Métodos estudo observacional transversal. Foram analisadas amostras de fala de 15 participantes de um programa de reabilitação auditiva, que consistiam na prova de fonologia do ABFW (ABFW - Teste de Linguagem Infantil nas Áreas de Fonologia, Vocabulário, Fluência e Pragmática) e na fala espontânea, adaptada do Protocolo de Avaliação de Voz do Deficiente Auditivo. Foi aplicado o teste de Wilcoxon para comparar os índices de Porcentagem de Consoantes Corretas (PCC) e Porcentagem de Consoantes Corretas revisado (PCC-r) das provas de fonologia e o teste de Mann-Whitney para comparar os referidos índices, em relação aos graus de inteligibilidade da fala espontânea. Também foi analisada a variabilidade de produção dos fonemas das provas de fonologia. Resultados verificou-se desvio leve nos índices de PCC e PCC-r para as provas de fonologia, com escores superiores para o PCC-r. Os participantes com médias maiores que 85% alcançaram inteligibilidade “Boa” e participantes com médias entre 85% e 50% apresentaram inteligibilidade “Regular/Insuficiente”. Os usuários de AASI não produziram adequadamente os fonemas /s/, /z/, /Ʒ/ /ɲ/, /l, /ʎ/, arquifonema /S/ e arquifonema /R/ e os usuários de IC, os fonemas /ʎ/ e arquifonema /R/. Conclusão o grupo estudado apresentou desvio leve nos índices de PCC e PCC-r, com médias superiores, quando considerada a distorção como acerto. Participantes com inteligibilidade “Boa” apresentaram maiores escores de PCC e PCC-r. Usuários de AASI não produziram fonemas fricativos adequadamente. Foram observadas produções com variação linguística social e regional.

“…The accuracy of consonant, consonant cluster and vowel production was assessed using a picture-naming task. This task has proved to reliably assess a child's ability to produce phonological contrasts in natural linguistic context (Edwards & Beckman, 2008;Mahshie et al, 2015). The picture-naming task used in this study was taken from the French EULALIES battery (Meloni et al, 2017).…”

Objective: This paper aims to investigate to what extent Cued Speech proficiency may improve speech production in French-speaking children with cochlear implants. Although cochlear implants facilitate speech comprehension in children with profound hearing loss, the auditory information provided remains degraded and phonological processing can remain impaired. In face-to-face interaction, Cued Speech manual gestures can be used to complement auditory and visual speech information, with established benefits for children with hearing impairment. A Cued Speech education might also have longer-term impacts on the speech processing abilities of these children. It can thus be expected that production accuracy will also benefit from Cued Speech exposure.Design: Thirty-two children with cochlear implants (20 with low Cued Speech proficiency vs 12 with high Cued Speech proficiency) and 81 children with typical hearing aged from 60 to 135 months took part in this study. Speech production was assessed using the picture-naming task from the EULALIES battery, which is designed to test the accuracy of spontaneous (non- imitative) phoneme production in isolated word context.Results: The results reveal first, that early implantation facilitates the development of phonological skills, but also that adequate exposure to Cued Speech compensates for late implantation. A positive effect of Cued Speech proficiency was indeed observed on consonant, consonant cluster and vowel production in children with cochlear implants.Conclusion: This study highlights long-term effects of Cued Speech education on speech production. This suggests that providing the child with a richer multimodal input might result in better specified phonological representations.

“…A follow-up study found that children with CIs produced less acoustic contrast between /s/ and /ʃ/ than children with NH, with /ʃ/-initial words being judged more intelligible than /s/-initial words (Reidy, Kristensen, Winn, Litovsky, & Edwards, 2017). Studies analyzing the speech of children with CIs using narrow transcription also provide evidence for fricative production confusions, particularly /ʃ/ substituting for /s/ (Baudonck, Dhooge, D'haeseleer, & Van Lierde, 2010;Mahshie, Core, & Larsen, 2015).…”

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.
