Remarks

Identifying information for a running recognition engine can be obtained using the SpeechRecognitionEngine.RecognizerInfo property on the SpeechRecognitionEngine.

A list of all supported SpeechRecognitionEngine configurations is expressed as a list of available RecognizerInfo instances obtained through the static method InstalledRecognizers.

Instances of RecognizerInfo can be used to construct an instance of SpeechRecognitionEngine with specific configuration using the SpeechRecognitionEngine(RecognizerInfo) constructor.

Example

The example below validates a given System.Globalization.CultureInfo and ID string against the permitted SpeechRecognitionEngine configurations, expressed as a list of RecognizerInfo objects.

If the System.Globalization.CultureInfo and ID string validate, a new instance of SpeechRecognitionEngine is created using an appropriate instance of RecognizerInfo.

private SpeechRecognitionEngine SelectRecognizer(CultureInfo requiredCulture, string requiredId) {
    // Select based on a specific recognizer configuration:
    SpeechRecognitionEngine speechRecognitionEngine=null;
    foreach (RecognizerInfo config in SpeechRecognitionEngine.InstalledRecognizers()) {
        if (config.Culture.Equals(requiredCulture) && config.Id== requiredId) {
            speechRecognitionEngine = new SpeechRecognitionEngine(config);
            break;
        }
    }
    return speechRecognitionEngine;
}
