Dynamically loadable phrase book libraries for spoken language grammars in an interactive system

摘要

A system comprises a voice application with which a user interacts, and at least one dynamically-loadable phrase book library, separate from the voice application, that comprises, for each of a plurality of different phrases of a particular language, a method comprising code that when executed causes the phrase to be played. The voice application invokes execution of a selected method of the dynamically-loadable phrase book library to cause a corresponding phrase to be played to the user. In this manner, the code that causes different phrases to be played is separated from the voice application. A method for designing such a system is also disclosed.
