Abstract
The present study compared the speech produced by persons with pseudobulbar palsy with that produced by a matched non-clinical population of normal speakers on a detailed inventory of 32 speech dimensions. The aim of the study was to determine whether, and to what extent, the perceptual characteristics of speech produced by speakers with pseudobulbar palsy differs from that produced by normal speakers. Results indicated that the pseudobulbar palsy group were significantly less intelligible than the control group, with deviant speech features being present in the five speech production processes of respiration, phonation, resonation, articulation and prosody.
