Abstract

The current invention provides a method and system for enabling a device function of a vehicle. A speech input stream is received at a telematics unit. A speech input context is determined for the received speech input stream. The received speech input stream is processed based on the determination and the device function of the vehicle is enabled responsive to the processed speech input stream. A vehicle device in control of the enabled device function of the vehicle is directed based on the processed speech input stream. A computer usable medium with suitable computer program code is employed for enabling a device function of a vehicle.

A method of obtaining information from speech at a vehicle, comprising:

(a) receiving at a telematics unit in a vehicle a first speech input spoken by an occupant of the vehicle;
(b) determining if telephone-related information has been requested based on the inclusion of numerical utterances in the first speech input;
(c) determining if navigation information has been requested based on the inclusion of numerical utterances followed by non-numerical utterances in the first speech input;
(d) enabling a navigation system of the vehicle based on the determination in step (c);
(e) contacting directory assistance in response to the determination in step (b);
(i) receiving at the telematics unit telephone-related information in the form of a second speech input sent to the vehicle from a remote facility via a wireless carrier system;
