This study examined the effect of listening practice on the ability of young adults to comprehend natural speech and DECtalk synthesized speech by having them perform a sentence verification task over a 5-day period. Results showed that response latencies of participants shortened in a similar fashion to sentences presented in both types of speech across the 5-day period, with latencies remaining significantly longer in response to DECtalk than to natural speech across the days. These results suggest that high-quality synthesized speech, such as DECtalk, can be useful in many human factors applications.
本研究通过让年轻人在5天时间内完成句子验证任务，考察了听力练习对其理解自然语音和DECtalk合成语音能力的影响。结果表明，在这5天里，参与者对两种语音呈现的句子的反应潜伏期以相似的方式缩短，但在整个时间段内，对DECtalk语音的反应潜伏期仍显著长于对自然语音的反应潜伏期。这些结果表明，高质量的合成语音，如DECtalk，在许多人为因素应用中可能会很有用。
