Abstract:

The envi ronment adaptive method plays an important part in improving the robustness of automatic speech recognition.PMC is reviewed briefly and improved to achieve bet ter performance in real adverse environment.The experiments have been done based on Cambridge' s HTK toolkit to implement the continuous Mandarin digit recognition in noisy environment
