METHOD FOR RESTORING SPECTRAL COMPONENTS ATTENUATED IN TEST DENOISED SPEECH SIGNAL AS A RESULT OF DENOISING TEST SPEECH SIGNAL

摘要

Spectral components attenuated in a test denoised speech signal as a result of denoising a test speech signal are restored by representing a training undistorted speech signal as a composition of training undistorted bases, and representing a training denoised speech signal as a composition of training distorted bases. The test denoised signal decomposed as a composition of the training distorted bases. The undistorted test speech signal is then estimated as the composition of the training undistorted bases that is identical to the composition of training distorted bases.
