USE OF REGRESSION IN NOISY SPEECH RECOGNITION

Abstract

In this study, we investigated the contribution of the multiple regression to robust noisy speech recognition in improving the recognition rates. When the noisy speech recognition process is carried out; first of all, an Affine Transformation is performed in order to map the feature vectors of noisy speech into those of clean speech. After transforming, the recognition step is achieved using the Common Vector Approach (CVA). We used several multiple linear as well as non-linear regression models to improve the recognition rates by adding non-linear terms into the model during the affine transformation stage. In the experimental study, the recognition rates of the noisy speech signals with 0 dB, 5 dB, 10dB, and 20 dB Signal-to-Noise Ratio (SNR) values have been obtained. Noisy speech which has 20, 10, 5, and 0 dB SNR is obtained using MATLAB by adding white Gaussian noise on the clean speech taken from the Texas Instruments (TI) Digit Database. Improvements are observed when non-linear terms are introduced into the model.
