In this paper Time Domain Least Mean Square (LMS) algorithm and Wavelet Transform Domain Least Mean Square (WDLMS) algorithm with Daubechies wavelets are used to minimize the undesired noise from speech signals. The performance of this algorithm using different Daubechies wavelets db1, db5 and db10 are evaluated in presence of car noise at different signal to noise ratio (SNR) levels. WDLMS algorithm performed better than LMS algorithm at all SNRs for Daubechies wavelets at different vanishing moments.
