Public Class RecognizerInfo
'Usage
Dim instance As RecognizerInfo

public class RecognizerInfo

Remarks

SpeechRecognitionEngine.RecognizerInfo provides identifying information for an initialized SpeechRecognitionEngine object.

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.

Examples

The example below 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;
}
