A new algorithm for the extraction of the fundamental frequency time-varying information is described. The algorithm is based on the iterative use of a linear filter with zero phase and monotonically decreasing frequency response (low pass). The results show that the method is both efficient and robust in noisy environments, providing an estimate for the locations of the closure and opening of the vocal chords. © 1990. (EN)
