Abstract :
This report introduces a new approach of FRM technique for a robust speech recognition system. We have already developed an intelligent filtering technique for robust speech recognition. In this method, a conventional FIR band-pass filter is applied on running log power spectrum. In order to improve the recognition accuracy, the designed FIR filter becomes considerably high order. Using a FRM filter, we can develop the robust speech recognition whose recognition ability is high enough and whose filtering order can be reduced low. Using this new FRM filter, some speech recognition experiments are shown in this report.
