Abstract(in English) | In this paper, some methods, which improve voice quality and suppress musical noise in noise cancellers based on spectrum suppression approach, have been discussed. First, in order to suppress musical noise, the spectrum is weighted so as to suppress the high frequency components, which are dominant in the musical noise. Second, in order to improve voice quality, the original noisy voice is added to the voice after noise cancellation. These methods have been simulated and compared to the conventional methods. The simulation results show the proposed methods can improve the voice quality and suppress the musical noise. However, the method adding the original noisy voice requires more proper threshold control. |
