<P>PROBLEM TO BE SOLVED: To provide a voice interactive device, a voice interactive method, and a voice interactive program, to perform exact recognition even when a subject changes during dialogs between an interactive person and a device. Ž<P>SOLUTION: Voice recognition of a user's voice data input from a microphone is performed using an execution model corresponding to a task being performed (S103). If a front face cannot be recognized (S113: NO), it is determined that the user interrupted the dialogs with the voice interactive device and began to talk with a third person, and the task being performed is interrupted (S141). The voice recognition of the dialogs with the third person is performed with all language models, and based on the recognition result, a prediction model is determined corresponding to the task after restarting of the dialogs with the voice interactive device. When the dialogs with the voice interactive device is restarted, voice recognition is performed using an execution model and the prediction model (S103, S121). Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
