| Abstract: | This paper uses the time-varied spectral analysis and the synthesis technology eliminate the noise from the noisy speech through the frame-overlapping-spectral subtraction method which accords with the characteristic of constant changing speech. The test verifies that this method can effectively eliminate the disturbance of noise to get the enhanced speech, and ensure the non-loss of the intelligibility and the naturalness of speech. |
