Patent number: 8346550Abstract: 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.Type: GrantFiled: February 14, 2011Date of Patent: January 1, 2013Assignee: AT&T Intellectual Property II, L.P.Inventors: Richard C. Rose, Sarangarajan Pathasarathy, Aaron Edward Rosenberg, Shrikanth Sambasivan Narayanan
