In order to improve the speech quality of an electric larynx (EL) speaker, the speech signal of which is digitized by suitable means, the following steps are carried out: a) dividing a single-channel speech signal into a series of frequency channels by transferring it from a time domain into a discrete frequency domain; b) filtering out the modulation frequency of the EL by way of a high-pass or notch filter, in each frequency channel; and c) back-transforming the filtered speech signal from the frequency domain into the time domain and combining it into a single-channel output signal.
L'invention vise à améliorer la qualité de la voix d'un larynx électronique (EL) dont le signal vocal est numérisé par des moyens appropriés. A cet effet, les opérations suivantes sont réalisées: a) séparer un signal vocal monocanal en une série de canaux de fréquence par transfert du domaine temporel vers un domaine fréquentiel discret, b) filtrer la fréquence de modulation du EL au moyen d'un filtre passe-haut ou coupe-bande dans chaque canal de fréquence, et c) transformer à nouveau le signal vocal filtré du domaine fréquentiel vers le domaine temporel et le condenser en un signal de sortie monocanal.
