AudioStateChangedEventArgs Class
Provides data for the AudioStateChanged event of the SpeechRecognizer or the SpeechRecognitionEngine class.
Assembly: System.Speech (in System.Speech.dll)
The AudioStateChangedEventArgs type exposes the following members.
| Name | Description | |
|---|---|---|
 | 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.) |
The AudioState property gets a new instance of the AudioState enumeration when a SpeechRecognitionEngine.AudioStateChanged or a SpeechRecognizer.AudioStateChanged event is raised.
You can obtain the current state of the audio input using the AudioState property of the SpeechRecognizer or SpeechRecognitionEngine classes.
The following example demonstrates an event handler for handling the changing audio state of a speech recognition engine.
private SpeechRecognitionEngine sre; // Initialize the SpeechRecognitionEngine object. private void Initialize() { sre = new SpeechRecognitionEngine(); // Add a handler for the AudioStateChanged event. sre.AudioStateChanged += new EventHandler<AudioStateChangedEventArgs>(sre_AudioStateChanged); // Add other initialization code here. } // Handle the AudioStateChanged event. void sre_AudioStateChanged(object sender, AudioStateChangedEventArgs e) { AudioState newState = e.AudioState; // Handle event here. }
