The role of auditory temporal cues in the fluency of stuttering adults

et al. 2017

Purpose: to compare the frequency of disfluencies and speech rate in spontaneous speech and reading in adults with and without stuttering in non-altered and delayed auditory feedback (NAF, DAF).Methods: participants were 30 adults: 15 with Stuttering (Research Group -RG), and 15 without stuttering (Control Group -CG). The procedures were: audiological assessment and speech fluency evaluation in two listening conditions, normal and delayed auditory feedback (100 milliseconds delayed by Fono Tools software).Results: the DAF caused a significant improvement in the fluency of spontaneous speech in RG when compared to speech under NAF. The effect of DAF was different in CG, because it increased the common disfluencies and the total of disfluencies in spontaneous speech and reading, besides showing an increase in the frequency of stuttering--like disfluencies in reading. The intergroup analysis showed significant differences in the two speech tasks for the two listening conditions in the frequency of stuttering-like disfluencies and in the total of disfluencies, and in the flows of syllable and word-per--minute in the NAF.Conclusion: the results demonstrated that delayed auditory feedback promoted fluency in spontaneous speech of adults who stutter, without interfering in the speech rate. In non-stuttering adults an increase occurred in the number of common disfluencies and total of disfluencies as well as reduction of speech rate in spontaneous speech and reading.

Acoustically controlled auditory training in children with speech disfluency: a case report

et al. 2020

The purpose of this study was to verify the effect of the acoustically controlled auditory training on the speech fluency of children diagnosed with developmental stuttering. Two patients were submitted to speech fluency evaluation, basic audiological assessment, and central auditory processing assessment, before and after the intervention with the digital platform. Two male individuals (P1 and P2) participated in the research. They were respectively 8 and 9 years old, both were right-handed, native Brazilian Portuguese speakers, diagnosed with developmental stuttering, P1 presenting a moderate, and P2, a mild-to-moderate degree. There was an improvement in some auditory skills. However, there was no improvement in the speech fluency pattern in neither of the cases studied.

RESUMO Objetivo Verificar o efeito da retroalimentação auditiva atrasada na fluência da fala de indivíduos que gaguejam, com e sem alteração do processamento auditivo central. Método Participaram 20 indivíduos com gagueira, de sete a 17 anos, divididos em dois grupos, cada um com 10 indivíduos: Grupo Gagueira com Transtorno do Processamento Auditivo (GGTPA) e Grupo Gagueira (GG) sem alteração de processamento auditivo central. Os procedimentos foram: avaliação da fluência com retroalimentação auditiva habitual (RAH) e atrasada (RAA), e avaliação da gravidade da gagueira e do processamento auditivo central (PAC). O software Fono Tools foi utilizado para provocar o atraso de 100 milissegundos na retroalimentação auditiva. O teste dos Postos Sinalizados de Wilcoxon foi utilizado na análise intragrupos, e o teste de Mann-Whitney, na análise intergrupos. Resultados A RAA ocasionou no GG redução estatisticamente significante: no escore da frequência das disfluências típicas da gagueira na análise do Instrumento de Gravidade da Gagueira, na quantidade de bloqueios e de repetições de palavras monossilábicas, e na frequência de disfluências típicas da gagueira de duração. O atraso na retroalimentação auditiva não provocou efeitos estatisticamente significantes na fluência do GGTPA, grupo dos indivíduos com gagueira com alteração do PAC. Conclusão O efeito da retroalimentação auditiva atrasada na fala de indivíduos com gagueira foi diferente nos indivíduos com e sem alteração do processamento auditivo central, pois houve melhora da fluência apenas nos indivíduos sem alteração do PAC.

Temporal processing and long-latency auditory evoked potential in stutterers

Abstract: Stutterers have poor performance in temporal processing and higher latency values for N2 and P3 components.
