Abstract

Selon l'invention, un membre du public recevant une émission sur laquelle un récepteur est réglé est identifié par un système qui comprend un premier et un second microphone, une unité de suppression de bruit et une unité de reconnaissance vocale. Le premier ou le second microphone capte relativement une plus grande partie de signal vocal émis par le membre du public, tandis que l'autre microphone capte relativement une plus grande quantité du signal sonore émis par le récepteur. L'unité de suppression de bruit élimine sensiblement du signal vocal le signal de bruit. L'unité de reconnaissance vocale identifie ledit membre à partir de son signal vocal. Le premier et le second microphone, l'unité de suppression de bruit et l'unité de reconnaissance vocale peuvent être logés dans un boîtier tenu à la main ou pouvant être posé sur une table. Le système présenté peut également comprendre un audimètre passif servant à l'identification passive du membre, ainsi qu'un programme servant à identifier l'émission ou la chaîne sur laquelle le récepteur est réglé.
