| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We introduce a new noise suppression method by using a search strategy with multi-model compositions that includes the models of speech, noises, and their composites. Before noise suppression, a multi-pass and beam search is performed to find the best sequences of these models using noise acoustic models, noise-label n-gram models, and a noise-label lexicon. Noise suppression is frame-synchronously performed by the multiple models selected by the search. We evaluated this method using the E-Nightingale task, which contains voice memoranda spoken by nurses during actual work at hospitals. The proposed method obtained higher perfomance than that of the conventional method. | |
