Abstract
Abstract : In order to study the effects of time/frequency distortion on the prosodic features of speech, content-standard speech messages representing nine different emotions were subjected to reproduce ratios of 1.0, 1.8, 1.95, 2.05 and 2.15. These emotional speech stimuli were then presented to 50 Ss for identification of the intended emotion. The results demonstrated that identification scores were high for all emotions in the non-distortion condition and remained high for eight of the nine emotions under the most severe distortion condition. Compared to intelligibility scores which are more easily affected by time/frequency distortion, the information carried by the prosodic features of speech was robust and resistant to distortion.
