In this paper we are presenting a new algorithm for determining the fundamental frequency. The evaluation of pitch is a very difficult problem mainly because of the great variability and irregularity of the speech signals. The algorithm we are presenting is original so far as it relies on the implicit calculation of the autocorrelation of the temporal excitation signal. We have tested our algorithm on the Bagshaw database, created at the Center for Speech Technology Research at Edinburgh, which is primarily dedicated to the evaluation of algorithms estimating the fundamental frequency of speech. The results of our experiments show that our approach is very reliable.
