Abstract:
A common recommendation for communication partners of people with hearing loss is to speak clearly, but how effective is this simple instruction? Does everyone produce clear speech using the same strategies? Is clear speech produced when given minimal instruction the same as that produced when competing background noise is present? The present study examined the acoustic characteristics of passage level speech produced in four different conditions. Twelve talkers (8 female, 4 male) with a mean age of 21 years were audio recorded reading three paragraph length passages. In the first condition talkers read each passage conversationally as though speaking to a friend. In the three experimental conditions, talkers were instructed to speak as clearly as they could, speak as clearly as they could in the presence of multitalker babble, and speak as clearly as they could in the presence of speech-shaped noise. The babble and noise were presented over headphones at a level of 75 dB SPL. Acoustic measures examined changes in rate, frequency, and intensity across condition. Results of this study help clarify what changes talkers make in response to instructions to speak clearly compared to conditions with competing background noise.
