"Is There Anything Else...?" Role-Play Exploration To Use Response Times As A Relationship-Building Effect With Voice Assistants

The rapid advancement of language models is driving significant developments in voice assistants, enabling tasks to be performed without graphical or tactile user interfaces and fundamentally changing human-machine interaction. This article explores interaction with intelligent voice assistants (IVA) to improve usability and user experience. The focus is on designing the interaction between question and answer in the response time. The study demonstrates the effectiveness of the role-playing method in testing machine interactions in an accessible way, leading to the development of sound interactions. Furthermore, the study shows that the latency of a response can be divided into three distinct phases that can be deliberately designed. Additional findings indicate that the use of acoustic feedback and clear signals reduces uncertainty and enhances perceived response time.
