Adapting the agent’s speaking speed to that of the user is a promising approach
in the specific context of answering medical questionnaires via a dialogue system.
We aim to investigate whether users prefer to speak to a system that has a similar
speaking speed to their own rather than a different one. To address our reseach
question, we conducted a lab experiment with 18 participants. Using a withinsubjects-design, we measured their speaking speed and let them rate eleven different speaking rates of AI-generated audio files. The subjects preferred a medium
speaking speed the most. The correlation for the user’s own speaking speed and
their rating of the AI-voice’s speaking speed was not significant for any of the
eleven system speaking speeds, indicating that there is no relationship between
those two measures. The correlation between the speaking speed of the subjects
and their most preferred agent speaking speed was also not significant. Users’ own
speaking speeds do not seem to have an effect on how they perceive the agent’s
speaking speed. Previous research shows mixed results and suggests that there
may be a difference in perception of human speech versus synthesized speech},
