Speech interfaces to question-answering systems offer significant potential for find- ing information with phones and mo- bile networked devices. We describe a demonstration of spoken question answer- ing using a commercial dictation engine whose language models we have cus- tomized to questions, a Web-based text- prediction interface allowing quick cor- rection of errors, and an open-domain question-answering system, AnswerBus, which is freely available on the Web. We describe a small evaluation of the effect of recognition errors on the precision of the answers returned and make some con- crete recommendations for modifying a question-answering system for improving robustness to spoken input.
