Abstract: A syntactic analysis unit 104 performs a syntactic analysis for linguistic information on acquired user' speech (hereinafter simply referred to as “user speech”). A non-linguistic information analysis unit 106 analyzes non-linguistic information different from the linguistic information for the acquired user speech. A topic continuation determination unit 110 determines whether a topic of the current conversation should be continued or should be changed to a different topic according to the non-linguistic information analysis result. A response generation unit 120 generates a response according to a result of a determination by the topic continuation determination unit 110.

Abstract: A syntactic analysis unit 104 performs a syntactic analysis for linguistic information on acquired user speech. A non-linguistic information analysis unit 106 analyzes non-linguistic information for the acquired user speech, the non-linguistic information being different from the linguistic information. A filler length determination unit 120 determines a length of a filler according to a non-linguistic information analysis result. A filler generation unit 130 generates a filler having a length corresponding to a result of a determination by the filler length determination unit 120. The filler length determination unit 120 determines that a long filler should be generated when a syntactic analysis result needs to be used to generate a response and, otherwise, determines that a short filler should be generated. The voice output unit 150 outputs the response generated by the response generation unit 140 after outputting the filler.

Abstract: The present invention relates to a robot (1) configured to exhibit a robot identity and/or a robot personality at least partly through execution of computer-readable program code. The robot comprises a robot head (3) configured for connection to a face part (9; 9A, 9B) including a display surface, the robot being configured to cause the display of a face image depicting a face of said robot on said display surface. The robot head (3) is configured for detachable connection to said face part to allow detachable connection of different face parts (9; 9A, 9B) to the robot head, and the robot (1) is configured to automatically adapt said robot identity and/or said robot personality based on the face part currently being connected to the robot head (3). This allows a user of the robot to change character of the robot, i.e. to change the robot identity and/or personality, by connection of different face parts to the robot head.
