SpeechRecognition
Demonstrates
============
SpeechRecognition demonstrates the two speech recognition classes that are
present in System.Speech.Recognition namespace. System's default shared speech
recognizer can be used by SpeechRecognizer class. Users have limited control
over this shared recognizer. In Windows 7 the settings of the shared
recognizer can be accessed in Control Panel under "Ease of Access -> Speech
Recognition Options -> Advanced Speech Options". Creating a SpeechRecognizer
object will also activate the Windows Speech Recognition if it's not running
already. For more control over speech recognition, SpeechRecognitionEngine class
can be used.
This sample also demostrates how to load and use dictation grammars, how to use
the GrammarBuilder class to easily create grammars programatically and how to
load SRGS grammars from files. The events that are generated during the
recognition process are also logged to inform the user.
Sample Language Implementations
