7. A system comprising: a processor; a memory device; a voice application modeling component stored in the memory device and executable by the processor to provide a graphical modeling environment within which voice applications are graphically modeled, a listen element modeling component stored in the memory device and executable by the processor to provide a graphical modeling environment within which listen elements are graphically modeled, a graphically modeled listen element including properties to: associate the listen element model with one or more of the one or more data sources, and identify one or more data fields within the one or more data sources; and a translation component stored in the memory device and executable by the processor to translate graphically modeled voice applications into a target metadata representation, the translation enabling a modeled voice application to be processed in a voice application runtime environment; wherein the translation component, prior to translating a graphically modeled voice application into a target metadata representation, is executable to: retrieve data from each of the one or more data sources into respective local tables; for each local table, identifying matches between data in the local table with over-ride entries; and for each identified match with an over-ride entry, delete the matching entry in the local table and insert data from an over-ride configuration.

The system of claim 7 , wherein the translation component, when translating a graphically modeled voice application including a graphical model of a listen element: retrieves the data of the one or more identified data fields within the one or more data sources; and renders the retrieved data into a voice application grammar representation of the target metadata representation as a function of the graphical listen element properties.
