Effet de l’accélération artificielle du signal de parole sur la perception de la sévérité dans les dysarthries mixtes et ataxiques

Abstract : Does increase speaking rate improve speech intelligibility? To answer this question, we submitted a perceptive test to ten expert judges (speech therapist students) based on the hearing of different sentences read by 18 patients (6 patients with mixed dysarthria and Amyotrophic Lateral Sclerosis (ALS), 6 patients with ataxic dysarthria and Cerebellar Syndrome, and 6 control individuals). Time compressed speech leads to a significant gain in the perception of dysarthria level, and in speech rate. Conversely, the perception of articulatory quality remains unchanged for the whole group, but significant differences appear for some patients. Time compressed speech does not imply deterioration of the perception of neither dysarthria level nor articulatory production. Lastly, the highest gain in speech intelligibility concerns patients that have been judged the most slow and severe, in natural condition, and concerns therefore ALS patients particularly.
