摘要

A method of providing hands-free services using a mobile device having wireless access to computer-based services, comprising the steps of: (a) establishing a short-range wireless connection between a mobile device and one or more audio devices having at least a microphone and a speaker; (b) receiving at the mobile device speech that has been entered via the microphone by a user and transmitted over the short range wireless connection; (c) wirelessly transmitting the voice input from the mobile device to a voice recognition server providing Automatic Speech Recognition (ASR); (d) receiving at the mobile device a speech recognition result representing the content of the speech input; (e) determining a desired service by processing the speech recognition result using a first service identifying grammar, comprising identifying both a primary session context and one or more supplemental session contexts, and a desired service associated with the primary session context and a supplementary service for each of the supplementary session contexts; (f) determining a user service request by processing at least part of the speech recognition result using a second service-specific grammar associated with the desired service; (g) triggering the user service request and receiving a service response; (h) generating an audio message from the service response; and (i) presenting to the user the audio message via the loudspeaker.
