<P>PROBLEM TO BE SOLVED: To guide a user who utters to an utterance speed at which precision of speech recognition is excellent. <P>SOLUTION: A speech recognition part 223 recognizes a user's speech. An interaction management part 231 of action determining mechanism part 203 determines utterance contents of a robot according to the speech recognition result. An utterance speed detection part 206 finds the utterance speed of the user according to the speech recognition result. An utterance speed correction part 207 sets the utterance speed of the robot to a value smaller than the utterance speed of the user when the utterance speed of the user is larger than a speed at which precision of speech recognition is excellent, and sets the utterance speed of the robot to a value larger than the utterance speed of the user when the speaking speed of the user is smaller than the speed at which precision of speech recognition is excellent. A speech synthesis part 208 synthesizes a synthesized speech based upon the utterance contents determined by the interaction management part 231 to attain the utterance speed set by the utterance speed correction part 207, and outputs the speech from a speaker 72. This invention is applicable to the robot. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
