AI Article Synopsis
- The study examined speech patterns in 67 Parkinson's patients, 10 with neurological disorders, and 72 psychiatric patients through both listening and measuring durations.
- The Parkinson's group displayed the fastest speech rates, averaging 8.5 syllables per second, with some able to read sentences as fast as normal controls under stress.
- Notably, nearly half of the fast-speaking Parkinson's patients had shorter speaking times than their same-age peers, highlighting that speech control may be influenced by multiple factors beyond just brain lesions.
Article Abstract
Speech was studied subjectively (listening to recordings) and objectively (measurement of durations) in 67 Parkinsonians, 10 subjects with neurological disorders and 72 psychiatric patients. Acceleration of speech was greatest in the Parkinsonians (8.5 syllables per second). The total duration of a sentence read by several of tachylalic Parkinsonians was the same as that of normal control subjects reading as fast as they could. The duration of the pauses between words varied greatly in all categories of subjects. Almost half of the tachylalic Parkinsonians (10 out of 23) had a speaking time (excluding pauses) shorter than the shortest duration recorded among same-age normal controls. The authors attach particular significance to the cases in which tachylalia is observed in the absence of lesions in the central gray nuclei. These cases suggest that speech automatisms are regulated at several levels.
