Abstract
This study examined the potential usefulness of automated analysis of on-off speech patterns in the differentiation of stuttering from cluttering. Two groups of fifteen persons who had been previously classified as stutterers and clutterers served as subjects for this investigation. The data indicate that stutterers tend to have greater mean pause times and lower mean phonation times than clutterers. This result corresponds to the clinically observable characteristics of these groups. It is concluded that automated analysis of on-off speech patterns provides some basis for the differential diagnosis of stuttering from cluttering.
