Represents a speech recognition grammar used for free text dictation.

Namespace:  System.Speech.Recognition

public class DictationGrammar : Grammar

This class provides applications with a predefined language model that can process spoken user input into text. This class supports both default and custom DictationGrammar objects. For information about selecting a dictation grammar, see the DictationGrammar(String) constructor.

By default, the DictationGrammar language model is context free. It does not make use of specific words or word order to identify and interpret audio input. To add context to the dictation grammar, use the SetDictationContext method.

NoteNote:

DictationGrammar objects do not support the Priority property. DictationGrammar throws a NotSupportedException if Priority is set.
