This study investigated the effects of listening condition on speech rate judgment. Four listening conditions, in which a single sentence was presented at 21 speech rates ranging from 90 WPM to 250 WPM, were incorporated. These conditions included non-degraded, reverberation, band-pass filtered, and low-pass filtered conditions, each of which was selected to simulate listening conditions one might encounter in daily life. The participants were 20 young adults (20 to 40 years) with normal hearing. They were asked to make judgments of the rates of speech randomly presented in the four listening conditions using an equal-interval 5-step scale from too slow through too fast. Overall, speech rate was judged to be faster in the reverberant condition than in the other three conditions. These findings may have implications for auditory rehabilitation and counseling.
