Left hemisphere lateralization in unilateral upper motor neuron dysarthria via quantitative acoustic analysis

Left hemisphere lateralization in unilateral upper motor neuron dysarthria via quantitative acoustic analysis

Abstract This paper aimed to identify specific acoustic parameters F1, F2, and Vowel Space Area (VSA), Vowel Articulation Index (VAI), Formant Centralization Ratio (FCR) for evaluating speech in Mandarin-speaking individuals with Unilateral Upper Motor Neuron (UUMN) dysarthria. Additionally, it expl...
