Abstract: Computer-synthesized voices can help students learn information via recorded lectures or study aids. This experiment seeks to determine how differences in speed and pitch among synthesized voices affect students’ opinions about the voices and how well they remembered informative passages read by the voices. In the experiment, participants listened to five versions of a computerized voice, modified in speed and pitch, reading randomized passages. Subjects were asked to fill out questionnaires regarding characteristics and information from the passages. The data suggests that affective considerations are more prevalent than retention concerns when accumulating information from computerized voices.
