Towards Speech-Driven Question Answering: Experiments Using the NTCIR-3 Question Answering Collection. |
Abstract | ||
---|---|---|
We developed a method for producing statistical language models for speech-driven question answer- ing, which recognizes spoken questions with high ac- curacy. Our method uses a target collection (i.e., a document set from which answers are derived) to extract N-grams, and adapts them to the question- answering task by way of frozen patterns typically used in interrogative questions. In addition, our method magnifies N-gram statistics corresponding to frozen patterns in the original N-gram. For the pur- pose of experiments, we used dictated questions in the NTCIR-3 QAC test collection, and showed that our method outperformed a conventional language model adaptation method in terms of the speech recognition accuracy. |
