A pausa na produção da fala com comprometimento neurológico

Abstract

Dysarthria is associated with a deficit in phonemic planning or paralysis of specific speech articulators, besides a frequent velopharyngeal impairment and expected prosodic alterations. The main goal of this work is to describe the speech rhythm of a user of a palatal lift protheses by analyzing the way she signals some linguistic boundaries when reading a short story. Pause durations were measured and pauses were classified into six syntactic categories. The correlation coefficient between categories and durations is 62%, signaling that not all variance can be solely explained by syntax, but also by considering prosody as the interplay between linguistic knowledge and constraints of a biomechanical system. Despite her neuromotor impairment, the subject is able to use pauses to signal a prosodic hierarchy.

Análise acústica do padrão entoacional da fala de indivíduos com Transtorno do Espectro Autista

“…Klin (2006), in turn, adds that individuals with ASD generally exhibit a restricted spectrum of intonation patterns, presenting little relation in the communicative functioning of the statement (e.g., assertions of fact, humorous comments) (11) . In this sense, prosody can be seen as a suprasegment spanning two aspects: production, characterized by three classic parameters: duration (difference between two events), fundamental frequency and intensity; and perception, characterized by notions of perceived duration, height and volume (12) . In view of the above, the objective of the present study was to analyze prosodic elements of speech segments of individuals with autism spectrum disorder (ASD) and to compare with the control group, through an acoustic analysis.…”
