The effect of hearing loss on the intelligibility of synthetic speech

Abstract

Many factors affect the intelligibility of synthetic speech. One aspect that has been severely neglected in past work is hearing loss. In this study, we investigate whether pure-tone audiometry thresholds across a wide range of frequencies (0.25-20kHz) are correlated with participants' performance on a simple task that involves accurately recalling and processing reminders. Participants' scores correlate not only with thresholds in the frequency ranges commonly associated with speech, but also with extended high-frequency thresholds.
