RecognizerInfo Class
Represents information about a SpeechRecognizer or SpeechRecognitionEngine instance.
Namespace: System.Speech.Recognition
Assembly: System.Speech (in System.Speech.dll)
The RecognizerInfo type exposes the following members.
| Name | Description | |
|---|---|---|
 | AdditionalInfo | Gets additional information about a SpeechRecognizer or SpeechRecognitionEngine instance. |
| Culture | Gets the culture supported by a SpeechRecognizer or SpeechRecognitionEngine instance. |
| Description | Gets the description of a SpeechRecognizer or SpeechRecognitionEngine instance. |
| Id | Gets the identifier of a SpeechRecognizer or SpeechRecognitionEngine instance. |
| Name | Gets the friendly name of a SpeechRecognizer or SpeechRecognitionEngine instance. |
| SupportedAudioFormats | Gets the audio formats supported by a SpeechRecognizer or SpeechRecognitionEngine instance. |
| Name | Description | |
|---|---|---|
| Dispose | Disposes the RecognizerInfo object. |
| Equals(Object) | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
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.
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; }
