// 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.
}
