Abstract:
Dysarthria is collective name for motor speech disorders resulting from disturbance in the speech control mechanism due to the damage to the central or peripheral nervous systems. The speech intelligibility (SI) and communication ability of dysarthric patient are affected, impacting quality of life. Evaluation of dysarthric speech involves subjective and objective measurement which contains electrolaryngoscope, glottograph, electropalatography, nasalance evaluation, acoustic analysis including sonogram，spectrogram, perturbation and noise measurements. Multi-Dimensional Voice Program (MDVP) is a commonly used quantitative acoustic analysis of dysarthric speech. However, in the mainland of China, it is applied in researches on voice of normal people and patients with laryngological diseases and researches on voice characteristics of patients with Parkinson disease or cerebral palsy. To date, no study on the acoustic analysis using MDVP for dysarthric patients with cerebrovascular disease or traumatic brain injury is reported.
