title: Use of fuzzy weighted autocorrelation function for pitch extraction from noisy speech
abstract: An investigation is presented into the feasibility of incorporating a fuzzy weighting scheme into the calculation of an autocorrelation function for pitch extraction. Simulation results reveal that the proposed method provides better robustness against background noise than the conventional approaches for extracting pitch period in a noisy environment
