This research focuses on the acceptability of smart replies in emails and text messages. We propose a set of communication scenarios (both in a professional or personal context) to users and ask them what their reply would be in each scenario, offering them a pool smart replies to chose from or compose their own message. Our goal is to determine whether users find it interesting or not to use these suggestions. Analysis of the user responses will allow us to identify scenarios eliciting more user acceptance toward the smart replies. Finally, analysis of their answers and qualitative interviews will highlight how they perceive these technologies and their challenges (sincerity, agency, etc.).
