The second article in a two-part series (Hustad and Beukelman, 2001) reports on a study that examined effects of experimentally imposed topic cues, alphabet cues, and combined cues on listener comprehension of severely dysarthritic speech. Consistent with earlier intelligibility results, combined cues resulted in higher comprehension. Findings…

Purpose: This study addressed the effects of 3 different paradigms for scoring orthographic transcriptions of dysarthric speech on intelligibility scores. The study also examined whether there were differences in transcription accuracy among words from different linguistic classes. Method: Speech samples were collected from 12 speakers with…

This study examined word level intelligibility differences between DECTalk and MacinTalk speech synthesizers using the Modified Rhyme Test in an open format transcription task. Three groups of listeners participated: inexperienced listeners, speech-language pathologists, and speech synthesis experts. Within each group, listeners had higher…

A study compared intelligibility and speech rate differences following speaker implementation of 3 strategies (topic, alphabet, and combined topic and alphabet supplementation) and a habitual speech control condition for 5 speakers with severe dysarthria. Combined cues and alphabet cues yielded significantly higher intelligibility scores and…

Purpose: This study compared the influence of speaker-implemented iconic hand gestures and alphabet cues on speech intelligibility scores and strategy helpfulness ratings for 3 adults with cerebral palsy and dysarthria who differed from one another in their overall motor abilities. Method: A total of 144 listeners (48 per speaker) orthographically…
