public TimeSpan AudioPosition { get; }
member this.AudioPosition : TimeSpan

示例
下面的示例为或事件创建了一个处理程序 SpeechRecognizer.SpeechDetected SpeechRecognitionEngine.SpeechDetected 。The example below creates a handler for SpeechRecognizer.SpeechDetected or SpeechRecognitionEngine.SpeechDetected events. 每次检测到语音时,处理程序都会初始化显示,并显示状态信息,其中包括音频位置。The handler initializes a display each time speech is detected and displays status information, including audio position.
_recognizer.SpeechDetected +=
delegate(object sender, SpeechDetectedEventArgs eventArgs)
{
// Clear previous recognition information.
_audioDeviceStatusLabel.Enabled = true;
_audioDeviceStatusLabel.Visible = true;
Utils.DisplayAudioInputFormat(_audioStateLabel, _recognizer);
Utils.DisplayRecognizerState(_recognizerStateLabel, _recognizer.State);
Utils.DisplaySpeechDetected(_speechDetectedLabel, eventArgs.AudioPosition);
};
