7th International Workshop on Models and Analysis of Vocal Emissions for Biomedical Applications (MAVEBA 2011)
Parkinsonian speech is characterized by abnormally low voice intensity, with vocal decay, poor voice quality, reduced prosodic pitch and loudness inflection, imprecise vowels and consonants, dysrhythmia and short rushes of speech, mumbling, and reduced speech intelligibility. Recently, there have been new acoustic analysis methods to capture different aspects of these speech abnormalities. In this review, selected studies are summarized in order to illustrate the application of acoustic analysis of speech for the objective measurement and quantification of different aspects of parkinsonian dysarthria.
