LSU Master's Theses
Dysarthria refers to a group of neurogenic speech disorders which result in abnormal strength, speed, range, steadiness, tone, or accuracy of movements required for speech production. Although speech deficits of dysarthria are heterogeneous according to lesion sites and/or etiologies such as stroke, traumatic brain injury, cerebral palsy, Parkinson’s disease (PD), “imprecise consonants” has been known as one of the most prominent and frequently occurring features of dysarthria, which subsequently contributes to decreased speech intelligibility. The present study points out the paucity of acoustic data on consonants produced by speakers with dysarthria, especially by spectral analysis, and reports four spectral moment …
