System and method for providing a compensated speech recognition model for speech recognition
First Claim
1. An automatic speech recognition system, comprising:
- a memory that stores a user profile having data related to user vocal information and value associated with a probability of the user being in a particular acoustic environment based on a time of day;
a controller coupled with the memory that receives the user profile and then compensates at least one speech recognition model based on the user profile;
a communication device that receives speech utterances from the user over a network; and
a speech recognizer that recognizes the speech utterances by using the at least one compensated speech recognition model.

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 communications 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 controller used in an automatic speech recognition system, comprising:
-
a receiving section that receives speech utterances over a network from a user; a first section that determines user profile data related to user vocal information and value associated with a probability of the user being in a particular acoustic environment based on a time of day; and a second section that compensates a speech recognition model for recognizing the speech utterances based on the user profile data. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
