Configuring the resource manager service

The Nuance Resource Manager registers each instance of each Dragon Voice engine, and responds to application requests by allocating suitable resources for recognition and interpretation.

Management Station displays commonly-used properties on the Settings tab, and the following tables shows some of these properties. (Management Station does not display less-common parameters, but you can add them to the display at any time. For a complete list, see Speech product parameters.)
