An algorithm for estimating the vocal pulse positions and durations in an actual speech signal is described. Testing of the algorithm shows that it outperforms the best of the competitor algorithms in accuracy on the average by a factor of two. The algorithm is less sensitive to spectrum distortions in telephone channels, to various types of noise, and to instability in duration and amplitude of pulses produced by the voice source. The accuracy of the pulse position estimate is sufficient for a synchronous speech signal analysis, while the speed of signal processing makes the algorithm suitable for real-time operation.
