Abstract:
Objective:To explore the effectiveness of evaluating voice disorders in dysarthria patients after brain injury using speech production measurements and analyze their phonics characteristics.Methods:Twenty-nine patients were divided into a severe dysarthria group ( n=19) and a mild dysarthria group ( n=10) through the subjective evaluation of their speech, and then evaluated using a computer speech monitor. The maximum phonation time (MPT), maximum counting ability (MCA), basic frequency (F0), standard deviation of F0 (F0SD), F0 range, intensity, formant, and the distance of jaw and tongue movements were recorded. Results:All of the patients displayed abnormal MPTs and MCAs, with the average MPT and MCA of the severe dysarthria group significantly lower than the mild group′s averages. In the severe dysarthria group, the abnormal F0s, F0SDs, F2(i)s and tongue movement distances were significantly greater than in the mild group.Conclusions:Speech production measurements can be applied to evaluate the speech dysarthria patients after brain injury. It is very common for such patients to have impaired speech and respiratory function, so this is worthy of attention.
