Dysarthria is a neurogenic communication disorder affecting speech production. Significant differences in phonemic inventories and phonological patterns across the world's languages render generalization of disordered speech patterns from one language (e.g, English) to another (e.g., Cantonese) difficult. Capitalizing on existing methods in developing English-language dysarthric speech corpora, we develop a Cantonese corpus in order to investigate articulatory and prosodic characteristics of Cantonese dysarthric speech, focusing on speaking rate and pitch and loudness control. Currently, we have collected 7.5 and 2.5 hours of speech data from 11 dysarthric subjects and 5 control speakers respectively. Our preliminary analysis reveals the characteristics of Cantonese dysarthric speech are consistent with general properties of motor speech disorders found in other languages.
