Abstract(in English) | This paper proposes a new method for noise robust speech recognition, which is based on HMM composition and noisy frame detection. The proposed method detects noisy frames, and estimates their noise and SNR values by 2-steps detection. Recognition of input frames is performed by frame-wise model selection using the information in each frame. To evaluate the performance of the proposed method, connected-word recognition experiments were conducted. These results showed that the word correct rate of the proposed method is improved by a maximum of 19.5% compared to that of the use of multi-path models. |
