| Abstract(in English) | We propose combined N-gram models and descriptive grammars used in key-phrases spotting for robust speech understanding. We apply task dependent descriptive grammars to inside of key-phrases and word bigram models trained on similar task dialogue corpus to others. The combined language models for whole of sentence improve the accuracy in detecting key-phrases. Furthermore connecting key-phrase hypotheses based on inter key-phrases grammars realize robust speech understanding. The proposed approach was tested on data collected from realworld dialogue system on hotel retrieval task. The speech understanding strategy improves the accuracy in handling both in-grammar and out-of-grammar utterances over the conventional decoding approaches. |
