Toward a mutual adaptive interface: An interface induces a user’s adaptation and utilizes this induced adaptation, and vice versa

The purpose of this paper is to construct a meaning acquisition model as a basic technology for a mutual adaptive speech interface which can communicate smoothly with an everyday user. We then constructed the meaning acquisition model in consideration of the following assumptions: (1). the model needs to induce a user’s adaptation and to utilize this induced adaptation for the meaning acquisition processes, (2). the model focuses on the prosodic information, rather than phoneme information on which most past interface studies focused. As a result, we could confirm that this model could recognize the intentions/meanings of users’ verbal commands by inducing users’ adaptations and utilizing these for the meaning acquisition process when appropriate instructions were given to them from an experimenter. This result would complement the interface studies that focused only on phoneme information, and contribute to a customization or personalization technology for a speech interface system.
