چکیده:

In previous work the two dimensional root cepstrum (TDRC) has been introduced as a novel method of feature extraction [8]. It has
the advantage of an adjustableparameter which can be used to optimise the feature extraction process, reducing the dimensions of the feature matrix and simple computation. In the work described here, the TDRC method has been suggested as a robust technique for noisy speech recognition. Gaussian noise have been added to the all original speech to simulate a noisy environment and to have various
of SNR. A task of multi-speaker isolated word recognition is conducted to demonstrated the effectiveness of using these robust features. Experimental results suggest that this method is more robust against noise than original TDC.
