| Abstract: | Objective： To study speech enhancement method based on the signal sub-space. Methods： Speeches to which various noises were added was recorded by Cool Edit Pro2. 0,and analyzed and then dealt with by Matlab. Results： The ratio of noise and signal can be improved a lot by reading speech waveform and speech spectrum and using the sub-space decomposition. Conclusion： The method of speech enhancement based on signal sub-space has achieved satisfying effects in both subjective hearing and objective quota. |
