Exempel

I följande exempel definieras en händelsehanterare som samlar in information om en AudioSignalProblemOccurred händelse.

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.RecognizerAudioPosition);

  // Insert additional event handler code here.
}

Kommentarer

En instans av AudioSignalProblemOccurredEventArgs skapas när SpeechRecognitionEngine objektet eller SpeechRecognizer skapar en AudioSignalProblemOccurred händelse. Om du vill hämta information om en AudioSignalProblemOccurred händelse får du åtkomst till följande egenskaper i hanteraren för händelsen:

• AudioLevel

• AudioPosition

• AudioSignalProblem

• RecognizerAudioPosition

Egenskapen AudioPosition refererar till indataenhetens position i den genererade ljudströmmen. Egenskapen refererar däremot RecognizerAudioPosition till identifierarens position inom dess ljudindata. Dessa positioner kan vara olika. Mer information finns i Använda taligenkänningshändelser.

Egenskapen AudioSignalProblem anger vilket problem som uppstod.

AudioSignalProblemOccurredEventArgs härleds från EventArgs.
