Patients with Parkinson’s disease (PD) often develop alterations of speech rate that inhibit their ability to communicate effectively, which may worsen quality of life. Although altered speech rate is frequently attributed to hypokinesia (weakness or loss of movement) of the speech organs, newer studies suggest that it may actually stem from an underlying impairment of vocal pace performance (speed in voice production) in PD.
