Abstract

Phonological neighbourhood density (ND) and phonotactic probability (PROB) have been shown as important variables in speech output accuracy. We examined whether PROB and ND have an effect on output accuracy in English speakers after stroke when other key variables in output are controlled. We also looked at the significance of ND/PROB regarding differential diagnosis. Fourteen speakers showed a positive effect of PROB on accuracy. Only two individuals displayed a positive ND effect. No double dissociations regarding the ND/PROB effect were noted for individuals or for the group. Results are discussed regarding speech models and assessment/treatment of acquired output impairment.
