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