Patent Images
1. A transaction system comprising:
- a phrase database storing phrases grouped into equivalence classes;
a user interface configured to allow interaction with an interactive part of a transaction;
a recognition server coupled with the phrase database and the user interface and configured to;
formulate at least one formulated expression representing at least a portion of the interactive part, where each of the at least one formulated expression comprises a combination of one or more phrases from the phrase database;
generate a recognition grammar from phrases in the phrase database that fall within an equivalent class associated with the formulated expression;
derive transaction input by applying the recognition grammar to a response obtained via the user interface and with respect to the interactive part; and
enable a computing device to process a transaction based on the transaction input.

Abstract
The invention enables creation of grammar networks that can regulate, control, and define the content and scope of human-machine interaction in natural language voice user interfaces (NLVUI). The invention enables phrase-based modeling of generic structures of verbal interaction to be used for the purpose of automating part of the design of such grammar networks. Most particularly, the invention enables such grammar networks to be used in providing a voice-controlled user interface to human readable text data that is also machine-readable (such as a Web page, a word processing document, a PDF document, or a spreadsheet).
