| Abstract(in English) | A design of reduced phoneme set based on a language model is proposed. The reduction of the phoneme set improves discriminability of phonemes under the condition where the amount of training data is too small to train each phoneme model. On the other hand, it increases homophones that yield degradation of speech recognition. In the proposed approach, it is possible to reduce phonemes preventing degradation, regarding pronunciation/word sequence confusion rate calculated from N-grams in a language model. In an experiment, the phoneme set designed with proposed approach was applied to Japanese large vocabulary speech recognition system. The word error rate with the 10 phonemes set was 14.6%, while the error rate with full 39 phonemes set was 17.7%. The degradation was able to be suppressed in about 3%. |
