Method and apparatus for speech recognition incorporating location information
First Claim
1. A method of speech recognition, comprising:
- receiving voice input;
associating a confidence measure with each of a set of stored patterns according to how closely the stored pattern matches the voice input;
acquiring location information; and
modifying at least one of the confidence measures based upon the location information.

Abstract
A method and apparatus for speech recognition incorporating location information. The method comprises receiving voice input from a user, associating a confidence measure with each of a set of stored patterns according to how closely the stored pattern matches the voice input, acquiring location information, and modifying one or more of the confidence measures based upon the location information. The apparatus comprises a speech recognition circuit that provides confidence measures, circuitry for acquiring location information, and logic for modifying the confidence measures based on the location information. Exemplary applications such as voice-dialing in a mobile communication device are described.

25. A method for voice-dialing in a mobile communication device, comprising:
-
receiving voice input comprising a spoken label corresponding to a desired telephone number;
associating a confidence measure with each of a set of stored patterns according to how closely the stored pattern. matches the voice input, each pattern corresponding to a stored telephone number;
computing the difference between the greatest and next-to-greatest confidence measures;
dialing the stored telephone number corresponding to the greatest confidence measure if the difference exceeds a predetermined threshold; and
acquiring location information comprising the current location of the mobile communication device, modifying the confidence measures corresponding to one or more of the stored telephone numbers based upon the location information, and dialing the stored telephone number corresponding to the resulting greatest confidence measure if the difference is less than the predetermined threshold.
