MEDIDAS ACÚSTICAS DE DURAÇÃO E ÍNDICES PERCEPTIVO-AUDITIVOS EM FALANTES ASMÁTICAS E DISFÔNICAS

Abstract

Investigate the relationships between glottic and supraglottic settings, five women asthmatic and dysphonic and five no change (reference group) were subjected to recording words containing voicelles and voice plosives. Were extracted and normalized acoustic measures of Voice Onset Time (VOT) and duration of vowels adjacent, as well as auditory trial. The values of VOT and duration showed statistical differences in the sounds [p] [t] and [k]. In the auditory trail, errors were generated in the sounds [p] [t] followed by [b] and [d] in  dysphonic group. Changes in production and perception of voiceless plosive consonant segments were found in this population.
