Abstract

Single word speech intelligibility was evaluated in three groups: aphasia with apraxia of speech, aphasia with no apraxia of speech, and normal controls. Intelligibility was significantly lower in the two aphasic groups compared with the normal group and intelligibility did not differ significantly between the aphasia and apraxia of speech and the aphasia only groups. Seventy per cent of the speakers with apraxia of speech obtained intelligibility scores below the normal range and 80 % of the speakers with aphasia only obtained intelligibility scores within the normal range. There was a moderate, but statistically nonsignificant, correlation between intelligibility and severity of apraxia of speech on an eight- point rating scale.
