A method for openvocabulary speech-driven text retrieval

by Atsushi Fujii - in Proceedings of the 2002 Conference on Empirical Methods in Natural Language Processing, 2002
"... While recent retrieval techniques do not limit the number of index terms, out-ofvocabulary (OOV) words are crucial in speech recognition. Aiming at retrieving information with spoken queries, we fill the gap between speech recognition and text retrieval in terms of the vocabulary size. Given a spoke ..."

Effects of language modelling on speech-driven question answering

by Tomoyosi Akiba, Atsushi Fujii, Katunobu Itou - Proc. Interspeech 2004, Korea (cd-rom , 2004
"... We integrate automatic speech recognition (ASR) and question answering (QA) to realize a speech-driven QA system, and evaluate its performance. We adapt an Ngram language model to natural language questions, so that the input of our system can be recognized with a high accuracy. We target WH-questio ..."

Language modeling for multi-domain speech-driven text retrieval

by Katunobu Itou, Atsushi Fujii, Tetsuya Ishikawa - In IEEE Automatic Speech Recognition and Understanding Workshop , 2001
"... We report experimental results associated with speech-driven text retrieval, which facilitates retrieving information in multiple domains with spoken queries. Since users speak contents related to a target collection, we produce language models used for speech recognition based on the target collect ..."

Exploiting Dynamic Passage Retrieval for Spoken Question Recognition and Context Processing towards Speech-driven Information Access Dialogue

by Tomoyosi Akiba
"... Speech interfaces and dialogue processing abilities have promise for improving the utility of open-domain question answering (QA). We propose a novel method of resolving disambiguation problems arisen in those speech and dialogue enhanced QA tasks. The proposed method exploits passage retrieval, whi ..."
