The Grammar Compiler takes a plain-text grammar file (BNF) and compiles it into a finite state grammar file (FSG). The FSG file is what the speech engine uses at run time to determine which words and phrases are currently available for a user to say to your application.

Documentation on the Grammar compiler can be found in the Grammar Guide. The VoiceType Developer's Toolkit also includes the following utilities to assist you in evaluating grammars:

• FSGENUM.EXE - Enumerates the strings produced by the grammar.

• FSGTEST.EXE - Determines whether input strings are accepted by the grammar.

• FSGPRINT.EXE - Displays the graph that defines the grammar.

• TIDYGRAM.EXE - Used to combine the Finite State Grammer (FSG) and What Can I Say (WCS) files, allowing grammars to be displayed in the What Can I Say window.

The Grammar compiler and utilities are located in the TOOLKIT\SPEECH\BIN subdirectory.
