Title: SPEECH DIALOGUE DEVICE, SPEECH DIALOGUE METHOD, AND RECORDING MEDIUM
Abstract:
[Problem] In the prior art, it had not been possible to appropriately support speech dialogue involving multiple languages. [Solution] A speech dialogue device comprising: a receiver that detects the starting point to the ending point of utterance of input speech spoken in two or more different languages, and acquires speech data in this interval; a language identifier acquisition unit that acquires language identifiers that identify the languages of the input speech; a speech recognition unit that generates speech recognition results in the form of text in accordance with the input speech and the language identifiers; a dialogue control unit that inputs the speech recognition result text and the language identifiers, and maintains a history of dialogue even when the language identifiers change from the most recent identifiers, while generating output sentences of different content in accordance with the language identifiers; a speech synthesis unit that generates speech waveforms in accordance with the output sentences and the language identifiers; and a speech output unit that outputs speech corresponding to the speech waveforms acquired by the speech synthesis unit, whereby speech dialogue involving multiple languages can be appropriately supported.
