Abstract

L'invention concerne un téléphone de voiture (20) avec un système de limitation de volume sonore (25) comportant un récepteur d'entrée (21) et un émetteur de sortie (22) de téléphonie mobile aptes à communiquer par un réseau hertzien (RH) avec un poste distant (40), ainsi qu'un haut-parleur d'émission sonore (23) et un microphone de capture sonore (24) reliés respectivement au récepteur d'entrée (21) et à l'émetteur de sortie (22) via le système de limitation (25). Le système de limitation (25) comporte en liaison un module de détection d'empreinte de voix (27), un variateur de volume (30) et un équipement anti-écho (26). De plus, le module de détection (27) est agencé entre le récepteur d'entrée (21), et le variateur de volume (30), ce dernier étant relié au haut-parleur (23), et l'équipement anti-écho (25) est monté entre le microphone (24) et l'émetteur de sortie (22).
