| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper addresses robust front-end processing for automatic speech recognition in noise. The proposed method integrates voice activity detection (VAD) and noise suppression, and consists of three core techniques, i.e., (1) statistical model sharing, (2) Wiener filter design by using speech / non-speech probabilities, and (3) VAD improvement by using enhance speech. In addition, the proposed method can perform sequential processing without frame delay. In an evaluation, the proposed method significantly improves accuracy of concatenated speech recognition without frame delay. In addition, we investigate to combine cepstrum mean normalization and sequential acoustic model adaptation with the proposed method. | |
