With
dictation recognition, a recogniser matches from all
the word possibilities in a large dictionary and asserts
contextual analysis to ensure it returns the correct
word (i.e., spelling) for homonyms (e.g., right or write).
Unlike dictation recognition, grammar recognition is
context-free. A recogniser only matches against the
rule definitions in the grammar.
Context-free grammar recognition enables your applications
to capture data very efficiently. Grammars also enable
your applications to assert domain constraints to elevate
data capture accuracy automatically.
What is Grammar Management?
Grammar management enables you to:
- design and test grammars for high-performance
recognition,
- compile static grammars to deploy binary with
applications, and
- integrate dynamic grammar generation and compilation
as part of deployed applications.
Applications benefits include:
- enhanced performance with optimised grammars,
- added flexibility to run with information unknown until application configuration or runtime, and
- expanded adaptability to run with available technology on the deployed system.
What is GrammarKit?
Chant GrammarKit handles the complexities of generating, compiling, and persisting the compiled grammar binary.
It simplifies the process of managing grammars declared with Microsoft SAPI 5 XML Grammar, Nuance BNF+ (VoCon 3200), Java Speech Grammar Format (JSGF), W3C SRGS ABNF, and W3C SRGS XML grammar syntax to use with your favourite speech recogniser.
GrammarKit includes C++, C++Builder, Delphi, Java, .NET Framework, and Silverlight class libraries to support all your programming languages and provides sample projects for popular IDEs—such as the latest Visual Studio from Microsoft.
The class libraries can be integrated with 32-bit, 64-bit, and embedded applications.
Features
The goal of good grammar design is to maximise application performance. With GrammarKit you can:
- Generate syntax-independent and -specific grammars;
- Compile grammar source from buffer, file, resource, stream, and string formats;
- Persist compiled grammar binary to buffer, file, and stream formats;
- Generate pronunciation phonemes; and
- Dynamically switch among grammar compilers and syntax formats.
Chant GrammarKit handles the complexities of constructing, compiling, and persisting grammars. This allows you to distribute compiled grammar binary files with your application, generate and compile grammars as part of your deployed application, and optimise grammar enablement at runtime by using compiled binary files.
Recognizers have their own syntax for expressing grammars. GrammarKit supports the following recognizers and their grammar syntax:

Within Chant Developer Workbench, you can:
- Create and edit grammars in native grammar syntax;
- Generate word pronunciation phonemes;
- Edit word pronunciation phonemes (requires LexiconKit);
- Compile and debug grammars; and
- Test grammars with live audio (requires SpeechKit).
Grammar Management: Design, compile, test, and debug speech recognition grammars before deployment.
Grammar Editing: Edit speech SAPI 5, L&H BNF+, JSGF, and W3C grammars faster with built-in intelliprompt that suggests valid grammar syntax.
Syntax Error Debugging: Automatic syntax checking displays visual cues and syntax error messages in the Error window. Click on the error to take you to the location of it in the document window.
Grammar Compiling and Testing: Compile and test grammars with a click of a button. Review compiler messages in the output window. Speak into a microphone to test grammar.
Recognition Results: View recognition results in the Output window.
Recognition Events: Browse recognition events in the Events window.
Compilation Error Debugging: Browse compilation errors in the Error window. Click on the error to take you to the location of it in the document window.
