Abstract

In this paper, a new noise-immune algorithm for the pitch estimation of speech signals is introduced. The main features of this algorithm are its accurate pitch value estimation in severe noisy environments and its capability of also being used as a speech enhancer. The algorithm is based on both the principles of using an adaptive digital filter (ADF) as a self-tuning filter, first introduced by J.R. Widrow et al. (1975), and the use of the ADF for speech enhancement, as introduced by M.R. Sambour (1978)
