Abstract(in English) | This paper investigates acoustic models for utterance variation and their units to improve recognition performance. Using a phoneme or a word as a unit of the variation, the models for utterance variation were trained for frequently observable variation. The variation models sharing HMMs among these models were also examined. The models trained for excitedly uttered words reduced 15% of key word erorrs in sports commentary. The models trained for rapidly pronounced reduced words 10% of word errors in conversational news. The results also showed dependence of the variation upon words. |
