The Use of Computer Generated Tests to Select a Speaker for a Random Access Digital Audio System.
Utz, Walter J., Jr.
Computerized speech could enhance the effectiveness of computer-assisted instruction as an educational tool. Digital audio under computer control allows a very wide range of replies, but it poses special problems in the areas of listener attitudes and speaker intelligibility. This paper discusses the design and implementation of special tests to discover a speaker who would be most pleasing and intelligible to students using a random access digital audio in a computer-assisted instruction system. Auditions were for both amateur and professional speakers, male and female. Junior college students rated the voices for likeability and intelligibility. Those who scored highest in the two tests all had some professional voice training and spoke in a mid-range pitch. As was expected , there was a correlation between intelligibility and attitude. Appendices contain raw scores and illustrative figures. (JY)
