摘要: In a speech recognition system, the beginning of versus non-speech (a cough or noise) is distinguished by reverting to decision process whenever liklihood cost template (vocabulary) patterns, including silence, worse than predetermined threshold, established Joker Word which represents non-vocabulary word score and path in grammar graph.
