Publication number: 20160154788Abstract: A dialog manager and spoken dialog service having a dialog manager generated according to a method comprising selecting a top level flow controller based on application type, selecting available reusable subdialogs for each application part, developing a subdialog for each application part not having an available subdialog and testing and deploying the spoken dialog service using the selected top level flow controller, selected reusable subdialogs and developed subdialogs. The dialog manager capable of handling context shifts in a spoken dialog with a user. Application dependencies are established in the top level flow controller thus enabling the subdialogs to be reusable and to be capable of managing context shifts and mixed initiative dialogs.Type: ApplicationFiled: February 2, 2016Publication date: June 2, 2016Inventors: Giuseppe DI FABBRIZIO, Charles Alfred Lewis

Patent number: 8792627Abstract: A method and apparatus for providing a relevant content delivery service on networks such as packet networks, e.g., Voice over Internet Protocol (VoIP) and Service over Internet Protocol (SoIP) networks are disclosed. For example, the present method receives a request to initiate a call from a calling party to a called party. The method then establishes a communication connection between the calling party and the called party and a communication connection to a speech recognizer. The method monitors a conversation between the calling party and the called party using the speech recognizer for detecting one or more verbal triggers. Finally, the method delivers relevant content that is associated with any detected verbal triggers to the calling party and/or the called party.Type: GrantFiled: November 3, 2006Date of Patent: July 29, 2014Assignee: AT&T Intellectual Property II, L.P.Inventors: Lee Begeja, Giuseppe Di Fabbrizio, Charles Alfred Lewis, Benjamin J. Stern, Jay Wilpon

Patent number: 8630859Abstract: A method of developing a dialog manager for a spoken dialog service is disclosed. The method comprises selecting a top level flow controller based on application type, selecting available reusable subdialogs for each application part, developing a subdialog for each application part not having an available subdialog and testing and deploying the spoken dialog service using the selected top level flow controller, selected reusable subdialogs and developed subdialogs. The method enables a developer to create a dialog manager that has individual reusable dialog modules that operate independent of the dialog model of the other modules. Application dependencies and context shifts are defined independent of the subdialogs to enable them to be reusable. The spoken dialog server manages context shifts in the spoken dialog by transitioning between dialog modules and subdialog modules.Type: GrantFiled: March 14, 2008Date of Patent: January 14, 2014Assignee: AT&T Intellectual Property II, L.P.Inventors: Giuseppe DiFabbrizio, Charles Alfred Lewis

Patent number: 7778836Abstract: A system and method are disclosed for switching contexts within a spoken dialog between a user and a spoken dialog system. The spoken dialog system utilizes modular subdialogs that are invoked by at least one flow controller that is a finite state model and that associated with a dialog manager. The spoken dialog system includes a dialog manager with a flow controller and a reusable subdialog module. The method includes, while the spoken dialog is being controlled by the subdialog module that was invoked by the flow controller, receiving context-changing input associated with speech from a user that changes a dialog context and comparing the context-changing input to at least one context shift. And, if any of the context shifts are activated by the comparing step, then passing control of the spoken dialog to the flow controller with context shift message and destination state.Type: GrantFiled: August 19, 2008Date of Patent: August 17, 2010Assignee: AT&T Intellectual Property II, L.P.Inventors: Giuseppe Di Fabbrizio, Charles Alfred Lewis
