Patent number: 9058810Abstract: Speech recognition models are dynamically re-configurable based on user information, application information, background information such as background noise and transducer information such as transducer response characteristics to provide users with alternate input modes to keyboard text entry. Word recognition lattices are generated for each data field of an application and dynamically concatenated into a single word recognition lattice. A language model is applied to the concatenated word recognition lattice to determine the relationships between the word recognition lattices and repeated until the generated word recognition lattices are acceptable or differ from a predetermined value only by a threshold amount. These techniques of dynamic re-configurable speech recognition provide for deployment of speech recognition on small devices such as mobile phones and personal digital assistants as well environments such as office, home or vehicle while maintaining the accuracy of the speech recognition.Type: GrantFiled: March 26, 2012Date of Patent: June 16, 2015Assignee: AT&T Intellectual Property II, L.P.Inventors: Bojana Gajic, Shrikanth Sambasivan Narayanan, Sarangarajan Parthasarathy, Richard Cameron Rose, Aaron Edward Rosenberg

Patent number: 8750464Abstract: The invention provides a system and method for indexing and organizing voice mail message by the speaker of the message. One or more speaker models are created from voice mail messages received. As additional messages are left, each of the new messages are compared with existing speaker models to determine the identity of the callers of each of the new messages. The voice mail messages are organized within a user's mailbox by caller. Unknown callers may be identified and tagged by the user and then used to create new speaker models and/or update existing speaker models.Type: GrantFiled: November 28, 2012Date of Patent: June 10, 2014Assignee: AT&T Intellectual Property II, L.P.Inventors: Julia Hirschberg, Sarangarajan Parthasarathy, Aaron Edward Rosenberg, Stephen Whittaker

Patent number: 8571861Abstract: 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: November 30, 2012Date of Patent: October 29, 2013Assignee: AT&T Intellectual Property II, L.P.Inventors: Richard C. Rose, Sarangarajan Parthasarathy, Aaron Edward Rosenberg, Shrikanth Sambasivan Narayanan

Patent number: 8131552Abstract: The invention provides a system and method for automatically indexing and retrieving multimedia content. The method may include separating a multimedia data stream into audio, visual and text components, segmenting the audio, visual and text components based on semantic differences, identifying at least one target speaker using the audio and visual components, identifying a topic of the multimedia event using the segmented text and topic category models, generating a summary of the multimedia event based on the audio, visual and text components, the identified topic and the identified target speaker, and generating a multimedia description of the multimedia event based on the identified target speaker, the identified topic, and the generated summary.Type: GrantFiled: January 17, 2007Date of Patent: March 6, 2012Assignee: AT&T Intellectual Property II, L.P.Inventors: David Crawford Gibbon, Qian Huang, Zhu Liu, Aaron Edward Rosenberg, Behzad Shahraray

Patent number: 7930179Abstract: Systems and methods for unsupervised segmentation of multi-speaker speech or audio data by speaker. A front-end analysis is applied to input speech data to obtain feature vectors. The speech data is initially segmented and then clustered into groups of segments that correspond to different speakers. The clusters are iteratively modeled and resegmented to obtain stable speaker segmentations. The overlap between segmentation sets is checked to ensure successful speaker segmentation. Overlapping segments are combined and remodeled and resegmented. Optionally, the speech data is processed to produce a segmentation lattice to maximize the overall segmentation likelihood.Type: GrantFiled: October 2, 2007Date of Patent: April 19, 2011Assignee: AT&T Intellectual Property II, L.P.Inventors: Allen Louis Gorin, Zhu Liu, Sarangarajan Parthasarathy, Aaron Edward Rosenberg
