  • Patent number: 8818793
    Abstract: A clausifier and method of extracting clauses for spoken language understanding are disclosed. The method relates to generating a set of clauses from speech utterance text and comprises inserting at least one boundary tag in speech utterance text related to sentence boundaries, inserting at least one edit tag indicating a portion of the speech utterance text to remove, and inserting at least one conjunction tag within the speech utterance text. The result is a set of clauses that may be identified within the speech utterance text according to the inserted at least one boundary tag, at least one edit tag and at least one conjunction tag. The disclosed clausifier comprises a sentence boundary classifier, an edit detector classifier, and a conjunction detector classifier. The clausifier may comprise a single classifier or a plurality of classifiers to perform the steps of identifying sentence boundaries, editing text, and identifying conjunctions within the text.

  • Patent number: 8804694
    Abstract: In one example, handling a call at a first client device in a packet network is described. The first client device obtains device capabilities of a second client device in response to the call. The device capabilities are processed to determine whether the second client device is capable of graphical display or graphical interaction. If so, the first client device follows a multimodal call flow. Otherwise, the first client device follows a voice-only call flow.

  • Patent number: 8798990
    Abstract: Disclosed herein are systems and methods to incorporate human knowledge when developing and using statistical models for natural language understanding. The disclosed systems and methods embrace a data-driven approach to natural language understanding which progresses seamlessly along the continuum of availability of annotated collected data, from when there is no available annotated collected data to when there is any amount of annotated collected data.

  • Publication number: 20140149121
    Abstract: A voice-enabled help desk service is disclosed. The service comprises an automatic speech recognition module for recognizing speech from a user, a spoken language understanding module for understanding the output from the automatic speech recognition module, a dialog management module for generating a response to speech from the user, a natural voices text-to-speech synthesis module for synthesizing speech to generate the response to the user, and a frequently asked questions module. The frequently asked questions module handles frequently asked questions from the user by changing voices and providing predetermined prompts to answer frequently asked questions.

  • Publication number: 20140074477
    Abstract: A system and method are disclosed that improve automatic speech recognition in a spoken dialog system. The method comprises partitioning speech recognizer output into self-contained clauses, identifying a dialog act in each of the self-contained clauses, qualifying dialog acts by identifying a current domain object and/or a current domain action, and determining whether further qualification is possible for the current domain object and/or current domain action. If further qualification is possible, then the method comprises identifying another domain action and/or another domain object associated with the current domain object and/or current domain action, reassigning the another domain action and/or another domain object as the current domain action and/or current domain object and then recursively qualifying the new current domain action and/or current object. This process continues until nothing is left to qualify.

  • Publication number: 20140029746
    Abstract: A system and method to provide content and call attributes for a destination phone number using a click-to-dial connection includes accepting a query, retrieving links to a document, and searching through cached data using the query to identify relevant or destination number information. If no match is found, the method continues with accessing the document identified by the link for identifying relevant number information and creating a click-to-dial icon to link to the relevant numbers included in the relevant phone number information identified by the query. Next, a popup box for content relevant to the click-to-dial icon and a click feature on the popup box are created to retrieve call destination attributes for viewing by a user. Further, computer instructions create at least one communication connection between two communication devices after viewing call destination attributes.

  • Publication number: 20140011544
    Abstract: An arrangement for allowing “hands-free” access to DTMF-controlled systems, such as one's voice mail messaging systems, utilizes a speech-to-DTMF tone application that monitors the communication between the user and the DTMF-controlled system. A speech recognition unit is utilized to retrieve certain voice commands (e.g., “next”, “skip”, “repeat”, “forward”, etc.) when uttered by the user. The application then translates the received commands into the proper DTMF tone sequence used by the DTMF-controlled system and transmits the DTMF tones to the system. The application is particularly useful in the cell phone environment and avoids the necessity of the user to constantly switch between using the keypad and listening to messages/commands from the system.

  • Patent number: 8582556
    Abstract: Method and apparatus for maintaining state information on a client device configured for voice-over-internet protocol (VOIP) communication is described. In one example, a VOIP call between the client device and an endpoint device through a packet network is established. State information is sent from the client device to the endpoint device during the VOIP call. The state object having the state information embedded therein is received from the endpoint device at the client device. The state object is stored in the client device. The state object may be retrieved from the client device during the VOIP call or a subsequent VOIP call in response to an authenticated request from the endpoint device. Alternatively, the state object may be retrieved from the client device during a subsequent web session in response to an authenticated request from a host.

  • Patent number: 8532267
    Abstract: A method and a voice-operated arrangement for interacting with a dual-tone multifrequency (DTMF)-controlled system. A record, including representations of DTMF tones and associated with communicating with a remote DTMF-controlled system, is accessed. A communication link between a user voice-communication device and the remote DTMF-controlled system is established through a speech-to-DTMF tone application. A user voice command is translated, using the record, into at least one DTMF tone for interacting with the remote DTMF-controlled system.

  • Publication number: 20120022950
    Abstract: Systems and methods are provided for a voice message to text system supporting targeted advertisements. Voice messages received from users are converted to raw text messages that are normalized to insert proper punctuation and extract entity information. The normalized text and entity information are processed to extract concepts, such as critical phrases, from the normalized text. Extracted concepts are then matched to advertisements on an advertisement database having user selection criteria. Advertisements having selection criteria matching the extracted concepts are transmitted to the users, and the advertisers that placed the advertisements are charged fees for the advertisements. User profile information and user context information can additionally be used to select advertisements for transmission to users.
