SpeechRecognitionEngine.EmulateRecognize Method (String)

Synchronously simulate audio input to the recognition engine with a String.

Namespace: Microsoft.Speech.Recognition
Assembly: Microsoft.Speech (in microsoft.speech.dll)

Syntax

'Declaration




Parameters

  • inputText
    A String containing text used as an input phrase in place of audio input during recognition emulation.

Return Value

Returns an instance of RecognitionResult containing the results of speech recognition. The instance is null if recognition fails, or if the recognitionEngine is not enabled.

Remarks

Successful emulated recognition will generate the standard events also associated with audio recognition events such as SpeechRecognized.

Emulated recognition ignores new lines and extra white space and treats punctuation literally, rather than letting it define phrases.

Example

In the following example, an application obtains text input through a Textbox, and uses it to emulate speech recognition.

private void EmulateTextBox_KeyPress(object sender, KeyPressEventArgs eventArgs) {
    if ((Keys)eventArgs.KeyChar == Keys.Enter) {
RecognitionResult result = _recognitionEngine.EmulateRecognize(_emulateTextBox.Text);

    }
}
// Emulate when Button is pressed in the emulateTextBox.
private void _emulateButton_Click(object sender, EventArgs e) {
    RecognitionResult result = _recognitionEngine.EmulateRecognize(_emulateTextBox.Text);
}
