  • Patent number: 10109271
    Abstract: 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.

  • Publication number: 20160314206
    Abstract: 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.

  • Patent number: 9384280
    Abstract: A transceiver of a computing device may receive data from a query to provide to a search engine to perform a search. The computing device may negotiate, automatically to overcome a restriction to access a page of a set of top webpages in association with the search, a fee. A processor of the computing device may continue to search information associated with the query on the page using a machine learning function.

  • Patent number: 8595001
    Abstract: 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.

  • Patent number: 8170880
    Abstract: 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.

  • Patent number: 8150703
    Abstract: Systems are disclosed for operating a communications network. The system includes a module to buffer frames of a signal, and a module to determine an access delay. The system also includes a module to compress a portion of the signal based on the access delay by removing a first portion of a frame of the signal and generating an overlap-added segment from a first segment and a second segment of the frame. In another embodiment, the system includes a module to buffer frames of a signal, a module to establish a communication channel with a handset, and a module to determine an access delay. The system also includes a module to compress a portion of the signal based on the access delay by removing a first portion of a frame of the signal and generating an overlap-added segment from a first segment and a second segment of the frame.

  • Patent number: 8069038
    Abstract: A system and method are disclosed for extending the bandwidth of a narrowband signal such as a speech signal. The method applies a parametric approach to bandwidth extension but does not require training. The parametric representation relates to a discrete acoustic tube model (DATM). The method comprises computing narrowband linear predictive coefficients (LPCs) from a received narrowband speech signal, computing narrowband partial correlation coefficients (parcors) using recursion, computing Mnb area coefficients from the partial correlation coefficient, and extracting Mwb area coefficients using interpolation. Wideband parcors are computed from the Mwb area coefficients and wideband LPCs are computed from the wideband parcors.

  • Patent number: 7970909
    Abstract: 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.
