Abstract

L'invention concerne un système de détection d'activité vocale comportant plusieurs circuits de retard à paramètre audio connectés en série entre eux. Le premier des ces circuits est également connecté à un générateur à paramètre audio, à plusieurs circuits de mesure distants, chacun d'eux étant connecté à au moins deux des circuits de retard, et un circuit de moyennage, connecté aux circuits de mesure distants, plusieurs circuits de retard de moyennage connectés en série entre eux. Le premier de ces circuits de retard de moyennage est également connecté à la sortie du circuit de moyennage et à un circuit de logique numérique connecté aux circuits de retard de moyennage.
