US 2002/0059068 A1 · Systems and methods for automatic speech recognition

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.

Claims32

Dependent claims

An automatic speech recognition system, comprising:

a memory that stores data related to at least one of a communication device, transducer, vocal information and acoustic environmental data;
a controller coupled with the memory that determines the data of the at least one communications device, transducer, vocal information and acoustic environmental data, and then compensates at least one speech recognition model to reflect the data;
and
a speech recognizer that recognizes speech utterances by using the at least one compensated speech recognition model.
