| Abstract(in English) | In this report, a noise robust speech recognition system which has been already developed is extended. The noise robust speech mechanism in the recognition system has been designed on the moderation spectrum domain. By using high order FIR filtering method (RSF), any time varying noise components can be eliminated and by using dynamic rang adjustment method (DRA). Any influences on noise SNR can be compensated. However, these methods require quite high calculation cost, i.e., a large number of coefficients in RSF. In this report, the novel approach in which low calculation cost is only required, i.e., Running Spectrum Analysis (RSA) which employs only FFT in its processing, is developed. By using this proposed algorithm, the similar performance can be realized. |
