“…Moreover, these populations exhibited more significant fluctuation in fundamental frequency (F0) and amplitude (Am) during sustained constant vowel production. These abnormal features gradually improve after cochlear implantation (9–11). These results confirm that auditory input via CI contributes to the development of voice skills controlling pitch and loudness.…”

“…These results indicate that congenitally deaf people, regardless of their age at cochlear implantation, had a lower ability to maintain a constant voice pitch and loudness than normal controls, even more than 10 years after implantation. The previous study using the conventional sustained vowel production task reported that in congenitally deaf CI users, vF0 and vAm gradually improved but remained significantly larger than controls 7 years after cochlear implantation (11). Thus, our results imply that neither a longer duration of CI use nor earlier implantation age is sufficient for deaf children to develop normal-like speech motor control to maintain voice pitch and loudness.…”

“…Because of this limitation, CI users may not notice minute changes in their own voice during sustained vowel production, even if there is no obvious abnormality in their speech motor system development. Figure 2A also shows a slightly but significantly larger vF0 in the Early-CI group than in the Late-CI group, which probably reflects the shorter duration of CI use in the Early-CI group because vF0 gradually decreases over time after cochlear implantation (9,11).…”

Objective: Congenitally deaf children with a cochlear implant (CI) improve their speech production intelligibility, but their prosody, including stress and intonation produced by voice pitch and loudness changes, often differs from normal hearing people, which affects their fluent oral communication. This study is aimed to clarify abnormal characteristics of voice pitch and loudness control in CI recipients using a newly developed visually guided pitch change task. Methods: We included 13 normal hearing volunteers (NH group) and 17 congenitally deaf CI users who showed good speech intelligibility. The 17 CI users were divided into Early-CI and Late-CI groups, based on their age at implantation of 2.5 years. Using the visually guided pitch change task and acoustic voice analysis of sustained vowels, we assessed their vocal skills to maintain constant pitch and loudness and intentionally change the voice pitch independent from loudness. At the time of examination, the mean age was 24.1, 12.7, and 18.9 years in the NH, Early-CI, and Late-CI groups. Results: During constant vowel production, Early-CI and Late-CI groups showed more significant fluctuations in pitch and loudness than the NH group. However, when focusing on intentionally changing only the pitch of the voice, the Early-CI group was significantly better than the Late-CI group and comparable to the NH group in terms of their ability to change vocal pitch independently from loudness. Conclusion: Among congenitally deaf patients, age at implantation was associated with the development of voice skills to control voice pitch and loudness separately, which may influence their fluent prosody production.

“…34,35 Common short-term measurements of vocal stability-jitter and shimmer-which measure variation of pitch and loudness, respectively, within single utterances, have similarly been found to increase in hearing impaired individuals, 37 which is consistent with decreased vocal stability. Following CI, both jitter and shimmer decrease in some prelingually deaf children, 34,36,38 approaching normal ranges. Other studies have suggested that both jitter and shimmer in deaf children do not significantly differ from NH either before or after implantation.…”

Control of speech and voice in cochlear implant patients

Objective Hearing plays an important role in the learning and production of speech, but the benefits of cochlear implantation for such vocal control are unclear. Here, we present a perspective and review of recent work on the control of speech and voice following cochlear implantation. We further discuss insights provided on the mechanisms of normal vocal control and implications for future rehabilitative approaches. Data Sources Peer‐reviewed articles on speech and voice production in cochlear implant patients were identified from PUBMED. Relevant articles were supplemented with selected publications describing normal vocal control mechanisms and behaviors. Review Methods Publications that discussed speech and voice outcomes following cochlear implantation were chosen, with a focus on those presenting measurements of specific speech or voice parameters. Results Recent studies demonstrate that hearing restoration by cochlear implantation has significant effects on many aspects of voice and speech production. These include changes in vocal pitch and loudness, as well as improved control of both vowels and consonants. Despite these improvements, however, the speech of many implant recipients remains abnormal as compared to normal hearing individuals. Such differences likely result from the impoverished auditory feedback provided by the implant. Conclusions Cochlear implants provide valuable insights into the role of hearing in vocal production. Although implants improve vocal production for most patients, there remains considerable room for future study and therapeutic improvement. Laryngoscope, 129:2158–2163, 2019

“…It is defined as the ability to perform fast repetitions of relatively simple patterns composed of oppositional contractions (9) , which may suggest information about individuals' neuromotor integration and maturation (9) . This acoustic evaluation has been used in several cases and populations, such as in children with speech sound disorders (10) , cochlear implants (11) , and fluency disorder (12) , in neurological patients (13)(14)(15)(16) , healthy elderly individuals (17) , youngsters and children (18,19) , as well as in patients with behavioral dysphonia (20,21) . Considering the DDK evaluations in clinical speech-language practice, laryngeal DDK aims to investigate neuromotor control of vocal folds (22) , being used mainly for the assessment of voice disorders (13,15,17,18,20,22) .…”

RESUMO Objetivo Verificar e comparar os efeitos da terapia manual laríngea (TML) e da estimulação elétrica nervosa transcutânea (TENS) na diadococinesia laríngea de mulheres disfônicas. Método Participaram 20 mulheres com nódulos vocais, divididas igualmente por sorteio em: Grupo TML–aplicação de TML; Grupo TENS–aplicação de TENS; ambos receberam 12 sessões de tratamento, duas vezes por semana, 20 minutos cada, pelo mesmo terapeuta. As mulheres foram avaliadas quanto à diadococinesia (DDC) laríngea em três momentos, diagnóstico, pré-tratamento e pós-tratamento, o que produziu três grupos de medidas. A gravação da DDC foi realizada por meio da repetição entrecortada das vogais: /a/ e /i/. A análise da DDC foi realizada pelo programa Motor Speech Profile Advanced (MSP)-KayPentax. Os parâmetros da DDC das três avaliações foram comparados entre si pelo teste t pareado (p≤0,05). Resultados Parâmetros DDC se apresentaram semelhantes na fase sem tratamento, indicando que não houve variabilidade individual ao longo do tempo. Não houve modificação em relação à velocidade da DDC após intervenções, mas após TML, a DDC da vogal /i/ se apresentou mais estável em relação à duração do período e à intensidade das emissões. Estes resultados indicam que TML melhorou a coordenação de movimentos das pregas vocais à fonação. Não houve modificações dos parâmetros da DDC em relação à estabilidade das emissões após TENS. Conclusão TML promove maior regularidade de movimentos diadococinéticos das pregas vocais em mulheres disfônicas, o que amplia o conhecimento sobre o efeito do reequilíbrio da musculatura laríngea na função fonatória, já TENS não proporciona efeitos na diadococinesia laríngea.
