The effects of sidetone delay, syntactic structure, and grammaticalness (meaning-fulness) on the duration, sound pressure level, and phonemic errors within sentences were measured. Three handicapped groups of 10 each, consisting of aphasic, dysarthric, and mentally retarded subjects were used. Delayed sidetone significantly affected duration of (a) the different sentence structures, (b) levels of grammaticalness, and (c) type of speakers. Sidetone increased the SPL significantly. The kernel sentence as compared with the three transformations and the meaningful sentences as compared with less meaningful and the least meaningful sentences were affected least in duration and SPL by the delay. The analysis of phonetic errors showed the working of distinctive feature rules within the limit of semantic relevance of a language.
