This paper describes a robust speech documents retrieval system that uses voice input keywords. To solve the in- evitable problems which arise when the input to the system is speech, i.e. misrecognition, a novel method was devel- oped, where, before the retrieval processing, unproductive keyword candidates are discarded by a grouping process- ing using the similarity between words and the recognition score of keywords. In retrieval experiments, we used the proposed method to retrieve Japanese broadcast news doc- uments through voice keywords input to the system and showed its e ectiveness.
