Abstract
A voice recognition grammar (“VRG”) tool for facilitating the creation of speech grammars for speech recognition applications is described. The VRG tool 114 uses syntax diagrams to enable a developer to visually build vendor-independent speech recognition grammars. The grammars are built from visual components called blocks, which represent the elements of a grammar. Blocks are connected and assigned values to define a grammar. A grammar is built with the VRG tool within a “Construction Area” by selecting blocks from a “Tool Kit.” Every phrase must start with a start block and be completed with an end block, with the various grammar blocks being connected between them. Once the syntax for the grammar is constructed, using the aforementioned blocks labeled and defined appropriately, a grammar specific to the selected vendor may be generated and is then ready for use by a voice recognition application.
