Abstract

Voice assistants (Google, Alexa...) are technologies that are entering in homes and people's life, more and more every day. Beyond their usefulness and functionalities, there is an obvious interface between man and machine that has not been taken into consideration by companies that have developed their own assistant yet : the voice used for the assistant. This paper aims to measure the impact of the voice of these assistants on users reactions. Thanks to 15 interviews of users, the results suggest that the type of voice of the assistant influences the social presence and trust in the assistant. Nevertheless, unlike the literature on virtual agents and chatbots, our study reveals that realism strongly influences the trust ; a synthetic voice that perfectly mimics a human, on the contrary, has a negative effect on the perception of the assistant.
