A speech analyzer comprises a speech acquiring section, a frequency converting section, an autocorrelation section, and a pitch detecting section. The frequency converting section converts the speech signal acquired by the speech acquiring section into a frequency spectrum. The autocorrelation section determines an autocorrelation waveform by shifting the frequency spectrum along the frequency axis. The pitch detecting section determines the pith frequency from the distance between two local crests or troughs of the autocorrelation waveform.
La présente invention concerne un analyseur vocal comprenant une section d~acquisition de la voix, une section de conversion de fréquence, une section d'auto-corrélation et une section de détection de pas. La section de conversion de fréquence convertit le signal vocal acquis par la section d~acquisition de la voix en un spectre de fréquences. La section d~auto-corrélation détermine une forme d~onde d~auto-corrélation en déplaçant le spectre de fréquences le long de l'axe de fréquence. La section de détection de pas détermine la fréquence de pas à partir de la distance entre deux crêtes ou creux locaux de la forme d'onde d'auto-corrélation.
