Speech matters - Psychological aspects of artificial versus anthropomorphic system voices in user-companion interaction

Abstract

The design of this forthcoming study was created to investigate the influences of different system-voices on users while they interact with a simulated Companion-system. By using a Wizard of Oz experiment, we want to find out what kind of voice output (artificial vs. anthropomorphic) is better suited for keeping up users’ cooperation with a system while solving a task. The goal of this study is to gain a deeper understanding of influences of the speech-output in User-Companion Interaction. Users’ perceived trustworthiness towards the system, their experienced affective states and individual user characteristics as important mediators are the main focus of the present study.
