An Efficient F0 Determination Algorithm Based on the Implicit Calculation of the Autocorrelation of the Temporal Excitation Signal

Colloque avec actes et comité de lecture.In this paper we are presenting a new formulation for determining the fundamental frequency. The evaluation of the 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 Centre 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
