應用聲譜分析評估吶吃療效之臨床報告

Abstract

Dysarthria may be defined as a group of speech disorders resulting from disturbance in muscular control due to damage in the central or peripheral nervous system. It encompasses coexisting neurogenic disorders of several or all the basic processes of speech - respiration, phonation, articulation, resonance and prosody. Although auditory discrimination can provide subjective evaluation of dysarthric speech before and after treatment, objective evaluation can help us to establish standards for clinical evaluation of acoustic charade- ristics.Six dysarthric and four normal control subjects were evaluated in this study. Sound spectrographic analysis was done of speech samples in vowel prolongation /ah/, oral diadochokinetic movement /p ^ t ^ k ^ / and a 6-word sentence. The results show that differential diagnosis of dysarthria can be made from the spectrogram qualitatively, and the efficacy of treatment can be measured quantitatively. The sound spectrogram provides objectively more detailed and complete analysis of dysarthric speech. It is a significant tool for speech pathologist to use in clinical evaluation and research of dysarthric patients.
