Abstract:

speech enhancement is one of the techniques used to improve the quality of a speech signal. Noise is an important factor that effect any kind of speech signal. To remove the noise present in the speech signal different adaptive algorithms are used. In this paper, the performance is estimated by using adaptive algorithms like LMS, NLMS and AP algorithms respectively. The adaptive filtering is observed for noises at different frequencies such as 0db, 5db, 10d and 15db. These algorithms are used to analyze the speech signal quality. The effectiveness of these algorithms is simulated by using MATLAB 2020b software tool.
