US Patent:

7945903, May 17, 2011

Filed:

Apr 16, 2004

Appl. No.:

10/826062

Inventors:

Cecilia M. Castillo - Lebanon NJ, US
Theodore J. Roycraft - Califon NJ, US
James M. Lewis - Berkeley Heights NJ, US

Assignee:

AT&T Intellectual Property II, L.P. - Atlanta GA

International Classification:

G06F 9/45
G06F 9/44

US Classification:

717140, 717105

Abstract:

A method, system and module for automatically converting a call flow into a state-based representation are disclosed. The method comprises walking a call flow and converting each page of the call flow into a rule of a higher level representation of the call flow, augmenting the higher level representation with terminal symbols representing state variable assignments and comparisons associated with decision and computation shapes in the call flow and converting the higher level representation into a state-based representation.

Appl. No.:

10/812999

Inventors:

James Wilson - Berkeley Heights NJ, US
Theodore Roycraft - Califon NJ, US
Cecilia Castillo - Lebanon NJ, US

International Classification:

G10L015/14

US Classification:

704256000

Abstract:

A system and method for automatically generating a spoken dialog application is disclosed. In one embodiment, a graphical representation of a call flow is converted into a context free grammar representation, which is then converted into a finite state machine, which is then used as the basis for the spoken dialog application.

Cecilia Castillo - Lebanon NJ, US
Theodore Roycraft - Califon NJ, US
James Wilson - Berkeley Heights NJ, US

International Classification:

H04M 7/00

US Classification:

379220010

Abstract:

A method and apparatus for processing unique dialogs from a dialog system to identify paths through the dialog system, each unique dialog having a corresponding identified path and generating a visual call flow representation as a function of the identified paths of the dialog system, the call flow representation including nodes and edges connected to correspond to the identified paths.

International Classification:

G06F 17/20

US Classification:

704001000

Abstract:

Certain exemplary embodiments comprise a method comprising: for a graphical representation of a process, the graphical representation comprising a network comprising a plurality of nodes connected by directional arcs: converting the graphical representation to a context-free grammar notation; for each of the directional arcs, defining at least one function from a plurality of functions, the function dependant on state information of the nodes connected by the arc; and for each of the functions, generating source code.

Abstract:

A method, system and module for automatically validating dialogs associated with a spoken dialog service. The method comprises extracting key data from a dialog call detail record associated with a spoken dialog service, transmitting the key data as a dialog to a state-based representation (such as a finite-state machine) associated with a call-flow for the spoken dialog service and determining whether the dialog associated with the key data is a valid dialog for the call-flow.
