Abstract:
Because of advancements of speech and language processing, a number of spoken dialogue systems have been constructed. However, because most of them adopt existing text-to-speech synthesizers to generate output speech, it is rather difficult to reflect all the linguistic information that is obtained during the reply sentence generation. To resolve this situation, a framework must correctly reflect higher-level linguistic information, such as syntactic structure and discourse information, on the prosody of output speech: concept-to-speech conversion, where reply sentences are generated from information (to be transmitted) and converted into speech in a unified process. A spoken dialogue system for road guidance was constructed, and concept-to-speech conversion was realized in the system. The linguistic information of the generated sentence is handled in tag LISP form to retain the syntactic structures throughout the process. Moreover, a new method of sentence generation from concept was realized with this system: it handles a concept in phrase units and aggregates them to form a sentence. It is tested whether the linguistic information could be reflected properly on the prosody of output speech. Results of listening experiments verified the effectiveness of our proposed method.
