Intelligibility and phonetic contrast errors in highly intelligible speakers with amyotrophic lateral sclerosis.
Intelligibility data, phonetic contrast errors, and information regarding subsystem involvement were examined in 29 highly intelligible subjects (18 women and 11 men) with amyotrophic lateral sclerosis. Results are discussed in terms of data for individual subjects, the group as a whole, and for subgroups based on dysarthric status and gender. Of particular interest are findings that suggest early laryngeal involvement as well as gender-related differences for several contrasts.
