9.Summary of Research Results

In order to achieve the goal of an advanced human-machine dialogue system through spoken language, the project was conducted by the following subgroups: (1) recognition and understanding of spoken dialogue, (2) inference on speaker's intention and determination of system's optimum response, (3) language generation and speech synthesis for system's response, and (4) integration of these component techniques into a spoken dialogue system and demonstration of its validity.
The results obtained by each subgroup are: 1) techniques for coping with noises and variations of various origin; 2) understanding of spoken dialogue based on key phrase spotting, and use of topic-dependent language models for improved speech recognition; 3) optimum response generation based on past history of dialogue and prosody generation of system's response for ease and efficiency of understanding by the user; 4) integration of techniques developed in 1)〜3) into the design and construction of an intelligent system for academic information retrieval through spoken dialogue. The system is based on the use of key concepts, processing of synonymy as well as polysemy/homonymy of keywords, dialogue management based on user and system modeling, and estimation of the relevance of a retrieved item. The system has been successfully tested on academic information provided by NACSIS.
Thus the project has produced a number of novel techniques for realizing advanced human-machine spoken dialogue systems, and demonstrated their feasibility through constructing, for the first time in the world, an advanced and intelligent system for academic information retrieval based on spoken dialogue, thus fully achieving the original goal set at the start of the project.
