AudioSignalProblem Enumeration
Visual Studio 2010
Contains a list of possible problems in the audio signal coming in to a speech recognition engine.
Assembly: System.Speech (in System.Speech.dll)
The AudioSignalProblem property of the AudioSignalProblemOccurredEventArgs class gets a member of this enumeration when the SpeechRecognitionEngine or SpeechRecognizer raises a AudioSignalProblemOccurred event.
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:"); details.AppendFormat( " 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, e.recoEngineAudioPosition); // Insert additional event handler code here. }
