Patent number: 7933774Abstract: A system and method is provided for rapidly generating a new spoken dialog application. In one embodiment, a user experience person labels the transcribed data (e.g., 3000 utterances) using a set of interactive tools. The labeled data is then stored in a processed data database. During the labeling process, the user experience person not only groups utterances in various call type categories, but also flags (e.g., 100-200) specific utterances as positive and negative examples for use in an annotation guide. The labeled data in the processed data database can also be used to generate an initial natural language understanding (NLU) model.Type: GrantFiled: March 18, 2004Date of Patent: April 26, 2011Assignee: AT&T Intellectual Property II, L.P.Inventors: Lee Begeja, Mazin G. Rahim, Allen Louis Gorin, Behzad Shahraray, David Crawford Gibbon, Zhu Liu, Bernard S. Renger, Patrick Guy Haffner, Harris Drucker, Steven Hart Lewis

Patent number: 7933773Abstract: A natural language understanding monitoring system adapted to conduct an automated dialog with a user. If the system is unable to identify from the automated dialog, to at least a predetermined level of confidence, any one of a plurality of predetermined tasks as being a particular task that the user wants to have performed, the system makes a determination of the value of a probability that further automated dialog will enable the system to identify the particular task, and determines whether or not to conduct further automated dialog with the user, in an attempt to identify the particular task, based on the relative values of the determined probability and a predetermined threshold value. The probability value determination is based on inputs from the user during the automated dialog.Type: GrantFiled: March 25, 2009Date of Patent: April 26, 2011Assignee: AT&T Intellectual Property II, L.P.Inventors: Allen Louis Gorin, Irene Langkilde Geary, Marilyn Ann Walker, Jeremy H.

Publication number: 20110093268Abstract: An apparatus, a method, and a machine-readable medium are provided for characterizing differences between two language models. A group of utterances from each of a group of time domains are examined. One of a significant word change or a significant word class change within the plurality of utterances is determined. A first cluster of utterances including a word or a word class corresponding to the one of the significant word change or the significant word class change is generated from the utterances. A second cluster of utterances not including the word or the word class corresponding to the one of the significant word change or the significant word class change is generated from the utterances.Type: ApplicationFiled: September 14, 2010Publication date: April 21, 2011Applicant: AT&T Intellectual Property II, L.P.Inventors: Allen Louis Gorin, John Grothendieck, Jeremy Huntley Greet Wright

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

Publication number: 20100217597Abstract: Systems and methods for using an annotation guide to label utterances and speech data with a call type are disclosed. A method embodiment monitors labelers of speech data by presenting via a processor a test utterance to a labeler, receiving input from the labeler that selects a particular call type from a list of call types and determining via the processor if the labeler labeled the test utterance correctly. Based on the determining step, the method performs at least one of the following: revising the annotation guide, retraining the labeler or altering the test utterance.Type: ApplicationFiled: May 3, 2010Publication date: August 26, 2010Applicant: AT&T Intellectual Property II, LP via a transfer from AT&T Corp.Inventors: Lee Begeja, Richard Vandervoort Cox, Harris Drucker, David Crawford Gibbon, Allen Louis Gorin, Patrick Guy Haffner, Steven H.

Publication number: 20100049519Abstract: A system and a method are provided. A speech recognition processor receives unconstrained input speech and outputs a string of words. The speech recognition processor is based on a numeric language that represents a subset of a vocabulary. The subset includes a set of words identified as being for interpreting and understanding number strings. A numeric understanding processor contains classes of rules for converting the string of words into a sequence of digits. The speech recognition processor utilizes an acoustic model database. A validation database stores a set of valid sequences of digits. A string validation processor outputs validity information based on a comparison of a sequence of digits output by the numeric understanding processor with valid sequences of digits in the validation database.Type: ApplicationFiled: November 5, 2009Publication date: February 25, 2010Applicant: AT&T Corp.Inventors: Mazin G.

Patent number: 7620548Abstract: The invention concerns a method and system for detecting morphemes in a user's communication. The method may include recognizing a lattice of phone strings from the user's input communication, the lattice representing a distribution over the phone strings, and detecting morphemes in the user's input communication using the lattice. The morphemes may be acoustic and/or non-acoustic. The morphemes may represent any unit or sub-unit of communication including phones, diphones, phone-phrases, syllables, grammars, words, gestures, tablet strokes, body movements, mouse clicks, etc. The training speech may be verbal, non-verbal, a combination of verbal and non-verbal, or multimodal.Type: GrantFiled: September 13, 2007Date of Patent: November 17, 2009Assignee: AT&T Intellectual Property II, L.P.Inventors: Allen Louis Gorin, Dijana Petrovska-Delacretaz, Giuseppe Riccardi, Jeremy Huntley Wright

Patent number: 7567906Abstract: Systems and methods for generating an annotation guide. Speech data is organized and presented to a user. After the user selects some of the utterances in the speech data, the selected utterances are included in a class and/or call type. Additional utterances that belong to the class and/or call type can be found in the speech data using relevance feedback, data mining, data clustering, support vector machines, and the like. After a call type is complete, it is committed to the annotation guide. After all call types are completed, the annotation guide is generated.Type: GrantFiled: April 3, 2007Date of Patent: July 28, 2009Assignee: AT&T Intellectual Property II, L.P.Inventors: Lee Begeja, Harris Drucker, David Crawford Gibbon, Allen Louis Gorin, Patrick Guy Haffner, Steven H Lewis, Zhu Liu, Mazin G Rahim, Bernard S.

Patent number: 7529667Abstract: This invention concerns a method and system for monitoring an automated dialog system for the automatic recognition of language understanding errors based on a user's input communications. The method illustratively determines whether a probability of understanding the user's input communication exceeds a first threshold. If the first threshold is exceeded, further dialog is conducted with the user. Otherwise, the user may be directed to a human for assistance. The method also illustratively determines whether the probability also exceeds a second threshold, the second threshold being higher than the first. If so, then further dialog is conducted with the user using the current dialog strategy. However, if the probability falls between a first threshold and a second threshold, the dialog strategy may be adapted in order to improve the chances of conducting a successful dialog with the user.Type: GrantFiled: September 6, 2005Date of Patent: May 5, 2009Assignee: AT&T Intellectual Property IIInventors: Allen Louis Gorin, Irene Langkilde Geary, Marilyn Ann Walker, Jeremy H.
