TL;DR: Based in part on previous studies of speech of the hearing impaired, a profile has been designed to direct research on the acoustic or physiologic correlates of dysarthric intelligibility impairment and a word intelligibility test is proposed for use with Dysarthric speakers.
Abstract: The measurement of intelligibility in dysarthric individuals is a major concern in clinical assessment and management and in research on dysarthria. The measurement objective is complicated by the ...

TL;DR: A survey of approximately 460 patients with Parkinson's disease (PD) or multiple sclerosis (MS) shows that speech and swallowing difficulties are very frequent within these groups.
Abstract: A survey of approximately 460 patients with Parkinson's disease (PD) or multiple sclerosis (MS) shows that speech and swallowing difficulties are very frequent within these groups. Seventy percent of the PD patients and 44% of the MS patients had experienced impairment of speech and voice after the onset of their disease. Forty-one percent of the PD patients and 33% of the MS patients indicated impairment of chewing and swallowing abilities. The speech disorder was regarded as one of their greatest problems by 29% of the PD patients and by 16% of the MS patients. Only a small number of patients, 3% of the PD and 2% of the MS group, had received any speech therapy.

TL;DR: The results suggest that the dementia of PD is distinguishable from that of DAT: PD patients have prominent motor speech abnormalities, whereas DAT patients exhibit more profound language alterations.
Abstract: Speech and language alterations were assessed in 51 patients with Parkinson9s disease (PD) and 10 patients with dementia of the Alzheimer type (DAT). Thirty-five of the PD patients had no evidence of intellectual impairment on a conventional mental status questionnaire and 16 of the PD patients had dementia syndromes of comparable severity to the DAT patients. DAT produced significantly greater language disturbances, including anomia, decreased information content of spontaneous speech, and diminished word list generation. PD patients had significantly decreased phrase length, impaired speech melody, dysarthria, and agraphia. The results suggest that the dementia of PD is distinguishable from that of DAT: PD patients have prominent motor speech abnormalities, whereas DAT patients exhibit more profound language alterations.

TL;DR: Results revealed that dysarthric speakers exhibited smaller vowel space areas and less systematic changes in vowel space as a function of speaking rate, when compared to the neurologically intact speakers, suggesting that vowel space area is an important component of global estimates of speech intelligibility.
Abstract: The relationship between speaking rate, vowel space area, and speech intelligibility was studied in a group of 9 subjects with amyotrophic lateral sclerosis (ALS) and 9 age- and gender-matched cont...
