Dtmf | The Grammar object should expect DTMF tones similar to those found on a telephone. |
Voice | The Grammar object should expect spoken audio data. |
Remarks
The default mode for speech recognition grammars is Voice. There are 16 DTMF tones, 12 of which are commonly found on most telephones.
Although the Mode attribute is used to inform the Grammar object of the type of input to expect, it is not exposed by that object. To set the mode, a SrgsDocument must be created and a Grammar object can be instantiated with the resulting SrgsDocument object.
Example
string srgsDocumentFile = Path.Combine(Path.GetTempPath(), "srgsDocumentFile.xml");
SrgsDocument document = null;
GrammarBuilder builder = null;
Grammar grammar = null;
Choices firstThree = new Choices("1", "2", "3");
Choices nextThree = new Choices("4", "5", "6");
Choices lastThree = new Choices("7", "8", "9");
Choices keyPadChoices = new Choices(firstThree, nextThree, lastThree, new Choices("0"));
builder = new GrammarBuilder(keyPadChoices);
document = new SrgsDocument(builder);
document.Mode = SrgsGrammarMode.Dtmf;
grammar = new Grammar(document;
