| Abstract(in English) | In this report, the design of noise robust acoustic models is explained and its noise robustness based on these models is explored. The acoustic models are trained with noisy speech data under ordinary circumstances and thus its precision degrades considerably. In order to reduce such noise influence, a running spectrum analysis (RSA) is introduced. The acoustic models with RSA can realize distinct discrimination between two different phonemes where an conventional acoustic models cannot realize clear distance between them. From these results, noise robust continuous speech recognition can be developed. |
