Abstract:
Speech enhancement techniques are widely used to enhance the quality and intelligibility of the speech signal in the noisy environment. Conventional noise reduction methods introduce more residual noise and speech distortion. The existing algorithms fail when there are abrupt changes in the noise level. To overcome the shortcomings of the conventional methods, improved noise tracking algorithm is proposed in this paper for speech enhancement. The noise signal is estimated for the existing and the proposed methods. Results are simulated using LabVIEW. From the evaluated results it is observed that the proposed noise tracking algorithm improve the average noise power from 90% to 97% of the original noise signal power for various noise conditions.
