CA 2239892

A base station system (203, 303) in a wireless communication system (208, 308) establishes a link between a mobile station (200, 300) and a speech recognition system (209, 312). When the base station system (203, 303) determines that such a connection is required, the base station system (203, 303) instructs the mobile station (200, 300) to switch from a first codec (201) specific to human speech to a second codec (202) specific to speech recognition. Only after the switch between codecs in the mobile station (200, 300) does the base station system (203, 303) establish the link between the mobile station (200, 300) and the speech recognition system (209, 312).

L'invention porte sur un système de station de base (203, 303) d'un système de transmission sans fil (208, 308) qui établit une liaison entre une station mobile (200, 300) et un système de reconnaissance vocale (209, 312). Lorsque le système de station de base (203, 303) détermine que ce type de connexion est nécessaire, le système de station de base (203, 303) donne à la station mobile les instructions de commuter d'un premier codeur-décodeur (201) spécifique à la voix humaine à un second codeur-décodeur (202) spécifique à la reconnaissance vocale. Ce n'est qu'après la commutation entre les codeurs-décodeurs de la station mobile (200, 300) que le système de station de base établit la liaison entre la station mobile (200, 300) et le système de reconnaissance vocale (209, 312).
