Investigation of Rate-Controlled Speech for Training Applications
Abstract
Two experimental evaluations were conducted to obtain empirical data on the effects of rate-controlled speech variables upon the listening comprehension of Navy trainees using representative Navy training materials. The results of the first experiment indicated that the intelligibility of rate- controlled recordings produced by a selective deletion device was significantly better than the intelligibility of recordings produced by a systematic deletion device. The second experiment demonstrated that both speech rate and content difficulty have a significant, but essentially independent, effect upon listening comprehension. Flesch readability data suggest that the difficulty level of representative Navy training materials is too high for the intended population. The empirical data presented in the report provide a schematic guide for the application of rate-controlled speech to training content.
