title: Presentation rate in comprehension of natural and synthesized speech.
abstract: This study examined the effect of four presentation rates (approximately 130, 150, 170, and 190 words per minute) on the comprehension of natural and synthesized speech by having 96 subjects [1 man, 95 women ranging in age from 18 to 40 years (M=21.0)] perform a sentence-verification task. Analysis showed that, while their response latencies were significantly faster to natural than to synthesized speech, presentation rate did not have a significant effect on response latencies when sentences were presented at rates within the average speaking range (approximately 130 to 190 words per minute). Implications these findings may have for the use of synthesized speech in human factors applications are discussed.
