Characterizing intonation deficit in motor speech disorders: an autosegmental-metrical analysis of spontaneous speech in hypokinetic dysarthria, ataxic dysarthria, and foreign accent syndrome.

This study compared the intonation patterns of unimpaired participants and those with Parkinson's disease, ataxic dysarthria, and foreign accent syndrome to evaluate the autosegmental-metrical framework's potential for distinguishing types of MSDs from each other and from unimpaire speech.
