| Abstract: | Speech enhancement algorithm is also called as noise cancellation algorithm, with the rapid development of communications industry"s in modern society, the study of speech enhancement technology has practical significance. In this paper, firstly introduces the running environment of the algorithm which is the basic characteristics of speech signal and noise signal. Secondly, analyze the principle, major parameters and operation block diagram of three kinds of the classical speech enhancement algorithms in theory. Finally, makes the simulation experiment of speech enhancement algorithm based on statistical model as an example which verified the effect of speech enhancement. |
