Publication number: 20200320144Abstract: A method and system that comprises a first device and at least one server is disclosed. The first device is configured to receive a voice signal including a natural language query and to transmit first information derived from the voice signal. The at least one server is configured to determine search criteria from the first information, to search at least one web service based on the search criteria, and to transmit second information based on a result of the searching. The first device is configured to receive the second information and to output a voice response to the natural language query and provide, using a display of the first device, a list of selectable options, based on the second information. The first device or the at least one server is configured to provide, using machine learning, additional information based on natural language queries outside of the natural language query.Type: ApplicationFiled: May 1, 2020Publication date: October 8, 2020Applicant: Bampton TechnologiesInventors: Richard Vandervoort COX, Hossein ESLAMBOLCHI, Behzad NADJI, Mazin G.

Patent number: 10109271Abstract: A frame erasure concealment technique for a bitstream-based feature extractors in a speech recognition system particularly suited for use in a wireless communication system operates to “delete” each frame in which an erasure is declared. The deletions thus reduce the length of the observation sequence, but have been found to provide for sufficient speech recognition based on both single word and “string” tests of the deletion technique.Type: GrantFiled: May 19, 2014Date of Patent: October 23, 2018Assignee: NUANCE COMMUNICATIONS, INC.Inventors: Richard Vandervoort Cox, Hong Kook Kim

Publication number: 20160314206Abstract: A server may utilize a dialog engine and a search engine to extract key phrases from a received natural language query. A database may be searched for a set of webpages based on the extracted key phrases. A first response having a portion of the set of webpages may be transmitted. The server may continue, after the first response using a machine learning function without user search input, to search information associated with the received natural language query.Type: ApplicationFiled: June 30, 2016Publication date: October 27, 2016Applicant: Bampton Technologies, LLCInventors: Richard Vandervoort COX, Hossein ESLAMBOLCHI, Behzad NADJI, Mazin G.

Patent number: 8595001Abstract: A method applies a parametric approach to bandwidth extension but does not require training. The method computes narrowband linear predictive coefficients from a received narrowband speech signal, computes narrowband partial correlation coefficients using recursion, computes Mnb area coefficients from the partial correlation coefficient, and extracts Mwb area coefficients using interpolation. Wideband parcors are computed from the Mwb area coefficients and wideband LPCs are computed from the wideband parcors. The method further comprises synthesizing a wideband signal using the wideband LPCs and a wideband excitation signal, highpass filtering the synthesized wideband signal to produce a highband signal, and combining the highband signal with the original narrowband signal to generate a wideband signal.Type: GrantFiled: November 7, 2011Date of Patent: November 26, 2013Assignee: AT&T Intellectual Property II, L.P.Inventors: David Malah, Richard Vandervoort Cox

Patent number: 8170880Abstract: Systems and methods herein use an annotation guide to label utterances and speech data with a call type. A system practicing the 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 system revises the annotation guide, retrains the labeler, and/or alters the test utterance.Type: GrantFiled: May 3, 2010Date of Patent: May 1, 2012Assignee: AT&T Intellectual Property II, L.P.Inventors: Lee Begeja, Richard Vandervoort Cox, Harris Drucker, David Crawford Gibbon, Allen Louis Gorin, Patrick Guy Haffner, Steven H.

Patent number: 7970909Abstract: A method and system for associating concurrent communication sessions. First and second communication sessions are established. The first and second communication session correspond to a common user account and are active concurrently. The first and second communication sessions are associated with each other to share data between the first and second communication sessions. The first and second communication sessions can be data network and telephone communication sessions established by a web server and a telephony network server, respectively. An application server can connect the web server and the telephony server to associate the data network and telephone communication sessions and share data between the data network and telephone network communication sessions.Type: GrantFiled: June 22, 2006Date of Patent: June 28, 2011Assignee: AT&T Intellectual Property I, L.P.Inventors: Richard Vandervoort Cox, Benjamin J.
