Combien d'options dans les messages vocaux?

Abstract

This research focus on the effect of number of options of message of Interactice Voice Response, or IVR, (recorded human voice) multiple option messages and on the effect of linguistic marker on memorization of options. Participants were told to pay attention to the quality of speech interactions between users and an IVR system with a natural voice. They asked to recall system messages which suffixes were added. The suffix was either experimental (pseudoword), natural ("It's your turn [to speak]") or control (beep). Results showed that option recall was impaired when messages were longer and contained a suffix. These results confirm and specify recommendations for IVR prompt design.
