Resumo: This experimental study aimed at the phonetic-acoustic characterization of consonant clusters in CCV syllables. Children between 5 and 6 years old with typical speech and phonological disorders participated in the study. The results showed that the two groups are in the process of articulatory fine-tuning of the gestures involved in the production of CCV syllables, presenting the same acoustic events that characterize such refinement, such as devoicing, oral interruptions and multiple bursts. However, children with phonological disorders presented these acoustic events with greater frequency. For this group, we also found that the rhotic sound in CCV syllables was not produced; however, the VOT and the nuclear vowel had a longer duration when compared to the duration in the data of the typical speech group. These characteristics seem to show that children with atypical speech have phonological knowledge of the presence of a segment that is not yet produced by them.

Participaron en el estudio niños de entre 5 y 6 años con habla típica y con desviación fonológica. Los resultados demuestran que ambos grupos están en el proceso de perfeccionamiento articulatorio de los gestos involucrados en la producción de las sílabas CCV, presentando los mismos eventos acústicos que caracterizan esta mejora, como ensordecimiento, bloqueos orales y múltiples bursts. Sin embargo, los niños con desviación fonológica presentaron estos eventos acústicos con mayor frecuencia. Para ese grupo, también se constató que el rotico en sílabas CCV no se produjo; sin embargo, el VOT y las vocales núcleo tuvieron una duración más larga en comparación con la duración que se muestra en los datos del grupo de habla típica. Esas características parecen demostrar que los niños de habla atípica tienen conocimiento fonológico en relación con la presencia de un segmento que todavía no producen.Este estudo experimental objetivou a caracterização fonético-acústica de encontros consonantais em sílabas CCV. Participaram do estudo crianças entre 5 e 6 anos com fala típica e com desvio fonológico. Os resultados mostraram que os dois grupos estão em processo de refinamento articulatório dos gestos envolvidos na produção das sílabas CCV, apresentando os mesmos eventos acústicos que caracterizam tal refinamento, como desvozeamento, bloqueios orais e múltiplos bursts. No entanto, as crianças com desvio fonológico apresentaram esses eventos acústicos com maior ocorrência. Para esse grupo, foi constatado ainda que o rótico em sílabas CCV não foi produzido, no entanto, o VOT e as vogais núcleo apresentaram duração mais longa quando comparada à duração exibida nos dados do grupo de fala típica. Essas características parecem evidenciar que as crianças de fala atípica têm conhecimento fonológico quanto à presença de um segmento que ainda não é produzido por elas.Programa de Pós-Graduação em Linguística - UFSC2021-11-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionavaliado por paresPesquisa experimentalapplication/pdfhttps://periodicos.ufsc.br/index.php/forum/article/view/7655710.5007/1984-8412.2021.e76557Fórum Linguístico; Vol. 18 No. 3 (2021); 6562-6584Fórum Linguístico; Vol. 18 Núm. 3 (2021); 6562-6584Fórum Linguístico; v. 18 n. 3 (2021); 6562-65841984-84121415-8698reponame:Fórum Linguísticoinstname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/forum/article/view/76557/47678Copyright (c) 2021 Fórum Linguísticohttp://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessOliveira, Aline Mara deSeara, Izabel ChristineLima Jr, Ronaldo Mangueira2021-11-29T17:02:27Zoai:periodicos.ufsc.br:article/76557Revistahttps://periodicos.ufsc.br/index.php/forum/indexPUBhttps://periodicos.ufsc.br/index.php/forum/oaiportaldeperiodicos.bu@contato.ufsc.br || atilio.butturi@ufsc.br1984-84121984-8412opendoar:2023-01-12T16:40:42.148753Fórum Linguístico - Universidade Federal de Santa Catarina (UFSC)false
