Examples

The following example validates a given CultureInfo and identifier string against the permitted SpeechRecognitionEngine configurations, expressed as a list of RecognizerInfo objects.

If the CultureInfo and identifier string are valid, the example creates a new instance of SpeechRecognitionEngine using the RecognizerInfo instance as an argument.

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;  
}

Remarks

You can obtain identifying information for an initialized recognition engine using SpeechRecognizer.RecognizerInfo for a SpeechRecognizer object or SpeechRecognitionEngine.RecognizerInfo for a SpeechRecognitionEngine object.

The information returned in instances of RecognizerInfo obtained from a SpeechRecognizer is determined by the settings in the Speech Properties member of the Control Panel.

You can use instances of RecognizerInfo to construct a specific configuration of SpeechRecognitionEngine using the SpeechRecognitionEngine(RecognizerInfo) constructor.

The static method InstalledRecognizers returns a list of all available SpeechRecognitionEngine configurations as RecognizerInfo instances.
