文摘

Distinctive speech patterns in atypical Parkinsonian syndromes are very rare. We investigated consonant articulation across Parkinsonian and healthy speakers. Voice onset time of voiceless plosives was related to overall dysarthria severity. Duration of pre-voicing was significantly shorter only in multiple system atrophy. Voiced plosives in multiple system atrophy tended to be misclassified as voiceless.
