Chant Developer Workbench 2011, GrammarKit 4, and SpeechKit 7 provide support for W3C SRGS ABNF grammars.
The W3C SRGS ABNF grammar text file format is a Backus-Naur Form (BNF) grammar adapted for speech recognition. The W3C specification is Recognition Grammar Specification Version 1.0.
Chant Developer Workbench 2011 introduces support for creating, editing, and testing W3C SRGS ABNF grammars. The new editor provides intelliprompt assistance for fast syntax input and editing.
The steps to create a W3C SRGS ABNF grammar with Chant Developer Workbench and GrammarKit are as follows:
GrammarKit 4 introduces support for dynamically generating and compiling W3C SRGS ABNF grammars.
