Methods and systems to enable touch-free call origination using a communication device equipped with a microphone. The method comprises processing a first microphone signal at the device in an attempt to detect a spoken activation command potentially contained therein. Responsive to detection of a spoken activation command in the first microphone signal, the method continues by establishing a communication path between the device and a network entity to convey to the network entity a second microphone signal. Finally, the method comprises processing the second microphone signal at the network entity in an attempt to detect a call origination command potentially contained therein; and, responsive to detection of a call origination command in the second microphone signal, attempting establishment of a call in accordance with the detected call origination command. Thus, a call can be established without tactile interaction with the device and, moreover, with minimal computational load on the device.

Procédés et systèmes pour l'émission d'appel mains libres sur dispositif de communications équipé d'un microphone. Le procédé est le suivant : traitement de premier signal de microphone au dispositif pour tenter de détecter une commande vocale potentiellement inhérente au signal; suite à cette détection, établissement d'un trajet de communication entre le dispositif et une entité de réseau pour acheminer à cette entité un second signal de microphone ; enfin, traitement du second signal à l'entité de réseau pour tenter de détecter une commande d'émission d'appel potentiellement inhérente à ce signal ; et, suite à cette détection, tentative d'établissement d'appel selon ladite commande détectée. On peut ainsi établir un appel sans toucher le dispositif, et par ailleurs avec une charge informatique minime sur ce dispositif..
