About

One of the traditional therapies for restoring the ability of speech in aphasic patients is Melodic Intonation Therapy (MIT), in which everyday phrases are taught in a singing-like manner. The suggested mechanism for speech recovery is that because of the sharing of brain resources for language and music, the regions normally reserved for singing can be trained to help compensate the speech functions originally subserved by the damaged regions. However, this therapy has primarily been applied to speakers of non-tone languages, in which prosodic features carry a more important role than pitch features in conveying meanings. It remains unknown whether MIT will be equally applicable for speakers of tone languages, in which pitch features likely play a more important role. Another uncertainty concerns whether the efficacy of MIT can be extended to patients with expressive speech impairment due to dementia. This pilot study aims to find out the efficacy of MIT for speech-impaired dementia patients in different verbal tasks. The results of this study will provide preliminary empirical evidence to establish the utility of MIT for Cantonese speakers in Hong Kong.
