Abstract

In this study, the effect of affine transformation on speech recognition is examined in noisy environment. Noisy speech which has 20, 10, 5 and 0 dB SNR is obtained in Matlab medium by adding whitenoise on clean speech in the TI Digit Database. The recognition rates are evaluated after the training and test sets which include noisy speech are mapped into clean speech by using Affine Transformations.
