Method and equipment of pattern recognition, its program and its recording medium

摘要: The present invention provides a method and equipment of pattern recognition capable efficiently pruning partial hypotheses without lowering accuracy, its program, recording medium. In second search unit, likelihood calculation unit calculates an acoustic by matching time series data feature parameters against lexical tree stored in database model third to determine accumulated accumulating the direction. A self-transition causes each hypothesis make process. An LR transition RL transition. reward attachment adds R(x) accordance with number reachable words raise likelihood. excludes less from targets.
