AudioSignalProblemOccurredEventArgs AudioSignalProblemOccurredEventArgs AudioSignalProblemOccurredEventArgs AudioSignalProblemOccurredEventArgs Class


Provides data for the AudioSignalProblemOccurred event of a SpeechRecognizer or a SpeechRecognitionEngine.

public ref class AudioSignalProblemOccurredEventArgs : EventArgs
public class AudioSignalProblemOccurredEventArgs : EventArgs
type AudioSignalProblemOccurredEventArgs = class
    inherit EventArgs
Public Class AudioSignalProblemOccurredEventArgs
Inherits EventArgs


The following example defines an event handler that gathers information about an AudioSignalProblemOccurred event.

private SpeechRecognitionEngine sre;  

// Initialize the speech recognition engine.  
private void Initialize()  
  sre = new SpeechRecognitionEngine();  

  // Add a handler for the AudioSignalProblemOccurred event.  
  sre.AudioSignalProblemOccurred += new EventHandler<AudioSignalProblemOccurredEventArgs>(sre_AudioSignalProblemOccurred);  

// Gather information when the AudioSignalProblemOccurred event is raised.  
void sre_AudioSignalProblemOccurred(object sender, AudioSignalProblemOccurredEventArgs e)  
  StringBuilder details = new StringBuilder();  

  details.AppendLine("Audio signal problem information:");  
    " Audio level:               {0}" + Environment.NewLine +  
    " Audio position:            {1}" + Environment.NewLine +  
    " Audio signal problem:      {2}" + Environment.NewLine +  
    " Recognition engine audio position: {3}" + Environment.NewLine,  
    e.AudioLevel, e.AudioPosition,  e.AudioSignalProblem,  

  // Insert additional event handler code here.  


An instance of AudioSignalProblemOccurredEventArgs is created when the SpeechRecognitionEngine or SpeechRecognizer object raises an AudioSignalProblemOccurred event. To obtain information related to an AudioSignalProblemOccurred event, access the following properties in the handler for the event:

The AudioPosition property references the input device's position in its generated audio stream. By contrast, the RecognizerAudioPosition property references the recognizer's position within its audio input. These positions can be different. For more information, see Using Speech Recognition Events.

The AudioSignalProblem property indicates which problem occurred.

AudioSignalProblemOccurredEventArgs derives from EventArgs.


AudioLevel AudioLevel AudioLevel AudioLevel

Gets the audio level associated with the event.

AudioPosition AudioPosition AudioPosition AudioPosition

Gets the position in the input device's audio stream that indicates where the problem occurred.

AudioSignalProblem AudioSignalProblem AudioSignalProblem AudioSignalProblem
