System and Method for Combining Geographic Metadata in Automatic Speech Recognition Language and Acoustic Models

摘要

Disclosed herein are systems, methods, and computer-readable storage media for a speech recognition application for directory assistance that is based on a user's spoken search query. The spoken search query is received by a portable device and portable device then determines its present location. Upon determining the location of the portable device, that information is incorporated into a local language model that is used to process the search query. Finally, the portable device outputs the results of the search query based on the local language model.

主权项

1. A method comprising:
incorporating a granularity description of a present location of a device into a local language model, the granularity description using topologically concentric locations to determine probabilities; combining the local language model with a global language model according to the probabilities, to yield a combined language model; and outputting, using the combined language model, results for a spoken query based on the present location and a term in the spoken user.
