Making Speech Synthesis More Accessible to Older People.

By Maria Wolters, Pauline Campbell, Christine DePlacido, Amy Liddell and David Owens


In this paper, we report on an experiment that tested users’\ud ability to understand the content of spoken auditory reminders.\ud Users heard meeting reminders and medication reminders spoken\ud in both a natural and a synthetic voice. Our results show that\ud older users can understand synthetic speech as well as younger\ud users provided that the prompt texts are well-designed, using\ud familiar words and contextual cues. As soon as unfamiliar and\ud complex words are introduced, users’ hearing affects how well\ud they can understand the synthetic voice, even if their hearing\ud would pass common screening tests for speech synthesis experiments.\ud Although hearing thresholds correlate best with users’\ud performance, central auditory processing may also influence\ud performance, especially when complex errors are made
