Zusammenfassung:A method for automatically switching to a channel for transmission on a portable radio is provided. In operation, a first microphone is assigned to respond to communications received on a primary channel and a second microphone is assigned to respond to communications received on a non-primary channel. The portable radio receives independent audio communications simultaneously on the primary channel and the non-primary channel when operating in a multi-watch mode. The portable radio determines a signal gain corresponding to a voice command received at the first and second microphones. When the signal gain for the first microphone is larger than the signal gain for the second microphone, the portable radio switches to a first talk-back channel to respond to communications received on the primary channel. Otherwise, the portable radio switches to a second talk-back channel to respond to communications received on the at least one non-primary channel. L'invention concerne un procédé de commutation automatique à un canal pour une transmission sur une radio portable. Selon le procédé, un premier microphone est désigné pour répondre à des communications reçues sur un canal primaire, et un second microphone est désigné pour répondre à des communications reçues sur un canal non-primaire. La radio portable reçoit des communications audio indépendantes, sur le canal principal et le canal non primaire simultanément, lorsque l'appareil fonctionne en mode multi-veille La radio portable détermine un gain de signal correspondant à une commande vocale reçue aux premier et second microphones. Lorsque le gain de signal du premier microphone est supérieur au gain de signal du second microphone, la radio portable se commute à un premier canal d'ordres pour répondre à des communications reçues sur le canal primaire. Autrement, la radio portable se commute à un second canal d'ordres pour répondre à des communications reçues sur le ou les canaux non primaires.
