摘要: [Problem] With conventional technology, it is impossible to appropriately support spoken dialog that is carried out in multiple languages. [Solution] A spoken dialog device includes: a receiving unit that detects a voice section from a start point to an end point of an input speech that is spoken in any of two or more different languages, and acquires speech data corresponding to the voice section; a language identifier acquisition unit that acquires a language identifier that identifies a language in which the input speech was spoken; a speech recognition unit that generates a text resulting from speech recognition, based on the input speech and the language identifier; a dialog control unit to which a text resulting from speech recognition and a language identifier are input, and that generates a different output sentence depending on a language identifier, while maintaining dialog history even when the language identifier is different from the previous language identifier; a speech synthesizing unit that generates a speech waveform based on the output sentence and the language identifier; and a speech output unit that outputs a speech that is based on a speech waveform generated by the speech synthesizing unit. With such a spoken dialog device, it is possible to appropriately support spoken dialog that is carried out in multiple languages.

摘要: In order to solve a conventional problem that, after a series of dialog between a user and a spoken dialog device has progressed to some extent, that user or another user cannot see or recognize a previous dialog status, a cross-lingual spoken dialog system is provided wherein, in a case in which an instruction from a user terminal is received by a pairing server, dialog information stored in a storage medium is transmitted to the user terminal. Accordingly, even after a series of dialog between a user and the spoken dialog device has progressed to some extent, that user or another user can see or recognize a previous dialog status.
