  • Mobile navigation of network-based electronic information using spoken input
    Patent number: 6757718
    Abstract: A system, method, and article of manufacture are provided for navigating an electronic data source by means of spoken language where a portion of the data link between a mobile information appliance of the user and the data source utilizes wireless communication. When a spoken input request is received from a user who is using the mobile information appliance, it is interpreted. The resulting interpretation of the request is thereupon used to automatically construct an operational navigation query to retrieve the desired information from one or more electronic network data sources, which is transmitted to the mobile information appliance.
    Type: Grant
    Filed: June 30, 2000
    Date of Patent: June 29, 2004
    Assignee: SRI International
    Inventors: Christine Halverson, Luc Julia, Dimitris Voutsas, Adam Cheyer
  • Navigating network-based electronic information using spoken input with multimodal error feedback
    Patent number: 6742021
    Abstract: A system, method, and article of manufacture are provided for navigating an electronic data source by means of spoken language. When a spoken input request is received from a user, it is interpreted. Additional input is solicited from the user in a modality different than the original request and used to refine the navigation query. The resulting interpretation of the request is thereupon used to automatically construct an operational navigation query to retrieve the desired information from one or more electronic network data sources.
    Type: Grant
    Filed: March 13, 2000
    Date of Patent: May 25, 2004
    Assignee: SRI International, Inc.
    Inventors: Christine Halverson, Luc Julia, Dimitris Voutsas, Aden J. Cheyer
  • System, method, and article of manufacture for agent-based navigation in a speech-based data navigation system
    Patent number: 6523061
    Abstract: A system, method, and article of manufacture are provided for navigating an electronic data source by means of spoken language where a portion of the data link between a mobile information appliance of the user and the data source utilizes wireless communication. When a spoken input request is received from a user, it is interpreted. The resulting interpretation of the request is thereupon used to automatically construct an operational navigation query. The navigation query is routed to one or more agents, which use the navigation query to retrieve the desired information from one or more electronic network data sources.
    Type: Grant

    Date of Patent: February 18, 2003
    Assignee: SRI International, Inc.

  • Accessing network-based electronic information through scripted online interfaces using spoken input
    Patent number: 6513063
    Abstract: A system, method, and article of manufacture are provided for navigating an electronic data source that has a scripted online interface by means of spoken input. When a spoken request is received from a user, it is interpreted. A navigation query is constructed based on the interpretation of the speech input and a template extracted by scraping an online scripted interface to the data source. The resulting interpretation of the request is thereupon used to automatically construct an operational navigation query to retrieve the desired information from one or more electronic network data sources, which is then transmitted to a client device of the user.
