Stady on the methed and system implementation of an isolated word recognition system used in noisy environment

After analyzing the speech features in noisy environment,an integrated method for isolated word recognition in noisy environment was proposed,and an experimental system was realized.The detail experiments show that the recognition rate of the system at the noise level about 80 dB is nearly equal to that of the system at noiseless condition,and the system can bear the most noise level about 100 dB.
