In this paper, we present an implementation of adaptive Wiener filtering as a speech enhancement technique for the pitch detection purpose from speech signals affected by noise. The adaptive Wiener filtering is used as a pre-processing stage for speech enhancement, and then a combined technique from Auto-Correlation Function (ACF) and Average Magnitude Difference Function (AMDF) is implemented to get accurate results. The main objective is to improve the process of detecting the fundamental frequency of the speech signal. The adaptive Wiener filter shows a superiority in the proposed pitch detection method as compared to the traditional Wiener filterandspectral subtraction.
