Raised when a speech recognizer performs recognition using the Grammar object.
public:
event EventHandler<System::Speech::Recognition::SpeechRecognizedEventArgs ^> ^ SpeechRecognized;
public event EventHandler<System.Speech.Recognition.SpeechRecognizedEventArgs> SpeechRecognized;
member this.SpeechRecognized : EventHandler<System.Speech.Recognition.SpeechRecognizedEventArgs>
Public Event SpeechRecognized As EventHandler(Of SpeechRecognizedEventArgs)
Public Custom Event SpeechRecognized As EventHandler(Of SpeechRecognizedEventArgs)
Event Type
Examples
The following example shows the use of an event handler for the Grammar object's SpeechRecognized event. It outputs the recognition results to the console.
public partial class Form1 : Form
{
SpeechRecognitionEngine sre;
public Form1()
{
InitializeComponent();
// Create an in-process speech recognizer.
sre = new SpeechRecognitionEngine();
// Configure input to the speech recognizer.
sre.SetInputToDefaultAudioDevice();
// Create a simple grammar and load it.
Grammar testGrammar = new Grammar(new GrammarBuilder("testing"));
sre.LoadGrammarAsync(testGrammar);
// Add a handler for the grammar's speech recognized event.
testGrammar.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(testGrammar_SpeechRecognized);
// Start asynchronous speech recognition.
sre.RecognizeAsync();
}
// Handle the grammar's SpeechRecognized event, output the recognized text.
void testGrammar_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
{
Console.WriteLine("Recognized text: " + e.Result.Text);
}
}
Remarks
The speech recognizer also raises a SpeechRecognized
event when it recognizes input. The Grammar object's SpeechRecognized event is raised prior to the speech recognizer's SpeechRecognized
event . For more information, see the SpeechRecognizer.SpeechRecognized, SpeechRecognitionEngine.SpeechRecognized, and RecognizeCompleted events.
Any tasks specific to a particular grammar should always be handled by handlers for the Grammar object's SpeechRecognized event.
