In this paper, a new Pitch Detection Algorithm (PDA) based on a Wavelet Transform (WT) Analyser of speech signals is proposed. It provides a value for the fundamental frequency at a pitch period rate. The method is described and evaluated in this paper. The algorithm uses both time and frequency information from the front-end analyser to detect relevant events for the estimation of the fundamental frequency.
