System and method for processing speech recognition
First Claim
1. A method of performing speech recognition, the method comprising:
- receiving a speech utterance, spoken by a user, at a service provider from a client device;
identifying a time associated with the speech utterance;
determining a probability associated with the user and the time, the probability being an expected type of background noise for the user at the time; and
based on the probability, applying a background noise model to recognize the speech utterance.

Abstract
An automatic speech recognition (ASR) system and method is provided for controlling the recognition of speech utterances generated by an end user operating a communications device. The ASR system and method can be used with a mobile device that is used in a communications network. The ASR system can be used for ASR of speech utterances input into a mobile device, to perform compensating techniques using at least one characteristic and for updating an ASR speech recognizer associated with the ASR system by determined and using a background noise value and a distortion value that is based on the features of the mobile device. The ASR system can be used to augment a limited data input capability of a mobile device, for example, caused by limited input devices physically located on the mobile device.

13. A system for performing speech recognition, the system comprising:
-
a processor; a first module configured to control a processor to receive a speech utterance, spoken by a user, at the system from a client device, wherein the client device is remote from the system; a second module configured to control a processor to identify a time associated with the speech utterance; a third module configured to control a processor to determine a probability associated with the user and the time, the probability being an expected type of background noise for the user at the time; and a fourth module configured to control a processor, based on the probability, to apply a background noise model to recognize the speech utterance. - View Dependent Claims (14, 15, 16, 17, 18)
