Relação entre percepção auditiva e produção vocal em implantados cocleares: uma revisão sistemática

Abstract

None of the selected studies were rated at level 1 of scientific evidence or grade A of recommendation, which is related to the methodological approach that can go with this subject matter. There is great lack of publications relating auditory perception and speech production in cochlear implant users. This gap is even greater when it comes to the adult population.

Parâmetros acústicos e perceptivoauditivos da voz de usuários de dispositivos auditivos

“…However, even with such a difference, the absolute values obtained in the auditory-perceptual analysis of the voice were similar, demonstrating that this information does not influence the voice sample of both groups. Although these were the results obtained in the present research, it is known that adults with prelingual HL, who were implanted late, when already an adult, can have important changes in their voice quality and speech production (15) . Thus, it is suggested that further studies be conducted to confirm this datum.…”

“…Furthermore, the higher degree of nasality and strain was notorious in the group with prelingual HL, a factor that can be associated with the incorrect velopharyngeal coordination during vocal production. It is further believed that the degree of nasality may have interfered with the overall impression on the voice quality, as nasality is an aspect commonly cited as a distinctive marker of the voice of people with HL (1,2,15,16) and that the subjects with a higher degree of nasality were those who, in this study, had a higher general degree of deviation in voice quality. This finding is possibly related to the difference in time of auditory deprivation and absence of feedback in both groups, as various studies present this factor as a great influence on the voice quality of the person with HL (4,18,24) .…”

“…Concerning the acoustic parameters of voice assessed in this study, extracted from the sustained emission, the values of the fundamental frequency (f0), jitter, shimmer, and HNR were greatly similar between the groups. However, studies demonstrate that subjects with HL that used devices such as CI or HA presented changes in these parameters when compared with normal hearing subjects (4,(15)(16)(17)(18)(19) . Moreover, a study verified reduced f0 values in subjects with HL after the CI surgery when compared with the preoperative group (2) .…”

Intersecções entre inclusão social e linguagem: práticas, contextos e desafios

“…Após o percurso da onda sonora durante as etapas do sistema auditivo periférico o estímulo recebido, ativa o sistema de processamento auditivo central, responsável pelas funções de discriminar, localizar e reconhecer o som, compreender e memorizar, (FILHO, 2013). De acordo com Capelli et al (2016), as tarefas desenvolvidas pelo Processamento Auditivo Central (PAC) são primordiais para a interpretação dos sons, e, por consequência, para a aquisição da língua oral.…”

Voz de crianças e adolescentes deficientes auditivos e pares ouvintes: influência da percepção auditiva da fala na produção vocal

“…Voice quality stands among the impact factors that can be mitigated (16) . Currently, some hearing-impaired children are undergoing a therapeutic process, benefiting from hearingrelated diagnostic and technological advances, while other children start intervention at a later age (17) .…”
