“…The results showed positive effects in individuals with stuttering without central auditory processing (SG) alterations, because the following reductions occurred: i) the frequency score of stuttering-like disfluencies of Stuttering Severity Instrument (17) ; (ii) the amount of blocks and monosyllabic words repetitions, and (iii) the total of disfluencies of duration. These data corroborate studies which show a decrease of the disfluencies in individuals who stutter under delayed listening condition (11)(12)(18)(19)(20)(21) . This increase in fluency represents a very relevant result for individuals with stuttering, for two main reasons: i) speech is the main form of human communication and its efficiency in transferring information depends on fluency (22) , and ii) the percentage of stuttered syllables or stuttering-like disfluencies is considered a counting measure of stuttering gold standard obtained by the speech language therapist (23) .…”

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.

“…However, despite the decline of SLD and TD in the moderate stuttering group, participants showed a tendency to decrease speech rate, considering that this is not a desirable effect. This result reinforces the previously idea observed in other studies, stating that auditory strategies should not be used in absolute way for all individuals who stutter, because not everyone is benefited, requiring, therefore, individualized tests 15,17,19,20,23 .…”

“…The first study used the delayed auditory feedback for people who stutter and found that the immediate effect of DAF has improved the fluency of the participants without affecting speech naturalness 18 . The other study compared the results in fluency of two groups of stutterers -one submitted only to speech therapy and another which received, associated with the therapy, the delay in auditory feedback -and found that the group which used the delay showed greater reduction of speech disruptions and higher gain in speech rate and production of information, compared to the group that did not use this device 19 .…”

Purpose: to compare the immediate effects of delayed auditory feedback in the oral reading task in school-age children with persistent developmental stuttering. Methods: this study was approved by the Institutional Ethics Committee (n° 0714/2013). Participated 16 school-children aged 8-17 years, 11 males and 5 females, divided into two experimental groups (EG1 and EG2) of 8 participants each; the EG1 composed of participants with moderate stuttering and EG2 with severe or very severe stuttering. The procedures used were audiologic evaluation, fluency assessment in spontaneous speech and evaluation of oral reading fluency in two listening situations: with Normal Auditory Feedback -NAF and Delayed -DAF. The Fono Tools software along with Andrea PureAudio USB -AS adapter and headset microphone Karsect HT-2 were used to cause the effect of the DAF and record speech.Results: the effect of delayed auditory feedback led to reduction of stuttering-like disfluencies in both groups, but the frequency of other disfluencies increased in moderate stuttering group and decreased in the group with severe / very severe stuttering and thus, total disfluencies showed a more significant decrease in EG2. There were statistically significant differences for the oral reading only in intergroup comparison for the stuttering-like disfluencies, at usual auditory feedback situation. Conclusions: the delayed auditory feedback did not cause significant effects during the oral reading in both groups, however there is a tendency of the effect be considered positive for the group with severe / very severe stuttering. Keywords: Speech, Language and Hearing Sciences; Speech Disorders; Reading; Stuttering; Feedback RESUMO Objetivo: comparar os efeitos imediatos do atraso na retroalimentação auditiva na tarefa de leitura oral em escolares com gagueira do desenvolvimento persistente. Métodos: estudo aprovado pelo Comitê de Ética da Instituição (n°0714/2013). Participaram 16 escolares, com idade de 8 a 17 anos, sendo 11 do gênero masculino e 5 do feminino, separados em dois Grupos Experimentais (GE1 e GE2) de 8 participantes cada; o GE1 composto de participantes com gagueira moderada e o GE2 com gagueira grave ou muito grave. Os procedimentos utilizados foram: avaliação audiológica, avaliação da fluência na fala espontânea e avaliação da fluência na leitura oral em duas condições de escuta: com Retroalimentação Auditiva Habitual -RAH e atrasada -RAA. O software Fono Tools junto com o Adaptador Andrea PureAudio USB-AS e microfone auricular Karsect HT-2 foram utilizados para provocar o efeito da RAA e gravar a fala. Resultados: o efeito da retroalimentação auditiva atrasada ocasionou redução das disfluências típicas da gagueira em ambos os grupos, porém a frequência de outras disfluências aumentou no grupo de gagueira moderada e diminuiu no grupo com gagueira grave/muito grave e, desta forma, o total de disfluências apresentou uma diminuição mais significativa no GE2. A diferença foi estatisticamente significante apenas na comparação intergrup...

“…Auditory Feedback Alteration (AFA) is the collective term for the conditions which involve the electronic alteration of the speech signal, in which the speakers perceive their speech differently from the usual one (16) . Delay and frequency alteration of auditory feedback are the most common alterations in the population of disfluent people (17)(18)(19)(20)(21)(22)(23)(24) . According to a study, these alterations cause the "choral speech phenomenon".…”

Introduction: Auditory feedback changes, in general, provide the increase of the speech fluency of people who stutter, but few studies have investigated the effects on speech of people who clutter. Purpose: To compare the speech rate and frequency of speech disruption in spontaneous speech and reading of adults with and without cluttering, with two different auditory feedbacks. Methods: Participants were 16 adults, divided into two groups: Research Group (G1) composed by eight cluttering adults; Control Group (G2), composed by 8 fluent adults, paired by age and gender to participants of G1. The participants of G1 should present at least 10% of common disfluencies, and speech rate higher than the standards expected for age and gender. The procedures used were audiology assessment and fluency evaluation (spontaneous speech and reading) in two listening conditions, with Non-Altered Auditory Feedback (NAF) and after with Delayed Auditory Feedback (DAF). Results: DAF caused reduction of flow of syllables per minute and frequency of common disfluencies in G1 during spontaneous speech task. In reading, there was a decrease in speech disruption and flow of syllables per minute, in G2, influenced by the effect of DAF. Conclusion:The delayed auditory feedback effect in adults who clutter was positive in spontaneous speech due the reduction of speech rate and common disfluencies that are the main manifestations of this disorder.
