A syntactic analysis unitperforms a syntactic analysis for linguistic information on acquired user' speech (hereinafter simply referred to as 'user speech'). A non-linguistic information analysis unitanalyzes non-linguistic information different from the linguistic information for the acquired user speech. A topic continuation determination unitdetermines 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 unitgenerates a response according to a result of a determination by the topic continuation determination unit

Voice interaction apparatus and voice interaction method

A syntactic analysis unitperforms a syntactic analysis for linguistic information on acquired user speech. A non-linguistic information analysis unitanalyzes non-linguistic information for the acquired user speech, the non-linguistic information being different from the linguistic information. A filler length determination unitdetermines a length of a filler according to a non-linguistic information analysis result. A filler generation unitgenerates a filler having a length corresponding to a result of a determination by the filler length determination unit. The filler length determination unitdetermines 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 unitoutputs the response generated by the response generation unitafter outputting the filler.
