| Abstract;Articulatory function for consonants was perceptually investigated in 58 individuals with dysarthria using an intelligibility test involving 100 Japanese monosyllabics. Major results include the following. 1. With respect to manner of articulation, intelligibility scores were high for nasal and fricative categories, and low for plosive, affricate, and flapped categories in all severity groups and in all types of dysarthria. 2. With respect to place of articulation, there were no significant differences in intelligibility scores among the 6 place categories in nearly all severity groups and in all types of dysarthria. 3. Intelligibility scores for unvoiced sounds were higher than those for voiced sounds in almost all severity groups and in all types of dysarthria. 4. Phonemic analysis showed that there was a remarkable difference among phonemes, with intelligibility scores ranging from 30.08% to 68.39%. Based on these findings, a treatment strategy for articulatory dysfunction in dysarthric speakers was discussed. (author abst.) |
