| Abstract(in English) | The high rate of False alarm is a serious problem in the Keyword Spotting methods based on the continuous Viterbi decoding using HMMS.To overcome this problem,in the paper,we propose a frame- synchronous Keyword Spotting method which extracts candidates for the word sequences accepted by a syntactic automaton with garbage words and keywords.The HMMs for the garbage words are estimated from the non-speech periods and the utterances for non-keywords which will be appeared in spontaneous input speech.Comparing the a- posteriori probabilities obtained by using the One-Pass search algorithm,candidates are extracted accurately.The detail of method and experimental results which compare garbage HMMs are described. |
