Abstract
A graphical tool is provided for allowing a developer of a speech-enabled application to create and edit grammars for speech recognition. The tool provides a user interface that has two editing modes, which the user can quickly and easily switch between. In the first editing mode, the user can specifying a grammar by writing or editing a Grammar Specification Language (GSL) listing. In response to such user inputs, the tool automatically generates or modifies a set of displayable graphical objects representing the grammar. In the second editing mode, the displayable objects are displayed, such that each object represents one or more speech expressions, and the logical relationships between the expressions are graphically represented. The user may edit the set of displayed objects in the second editing mode, including adding or deleting objects, modifying an expression represented by an object, or altering the logical relationships between the expressions. User inputs directed to the objects in the second editing mode are automatically reflected in the GSL listing when the user switches back to the first editing mode.
