Abstract

L'invention concerne un casque d'écoute comprenant : une première tête ayant une première unité haut-parleur ; une seconde tête ayant une seconde unité haut-parleur et un microphone placé à une position à l'intérieur du canal auditif externe d'un utilisateur lorsqu'il est porté ; une unité de communication pour communiquer avec un dispositif mobile ; et un contrôleur pour arrêter une sortie de signal audio à destination de la seconde unité haut-parleur lorsqu'un signal de capture de réaction acoustique est reçu du dispositif mobile via l'unité de communication. L'invention est ainsi apte à analyser efficacement un bruit provenant de l'extérieur et à capturer suffisamment la voix d'un utilisateur pour empêcher la survenue d'une réaction acoustique et d'un écho à la source. Le son reçu par l'utilisateur est clair et net et une précision de reconnaissance vocale peut être améliorée lorsque le procédé est appliqué à un dispositif de reconnaissance vocale.
