SpeechDetectedEventArgs.AudioPosition 属性

定义

获取语音在音频流中的检测位置。Gets the position in the audio stream where speech was detected.

public:
 property TimeSpan AudioPosition { TimeSpan get(); };
public TimeSpan AudioPosition { get; }
member this.AudioPosition : TimeSpan
Public ReadOnly Property AudioPosition As TimeSpan

属性值

TimeSpan

返回检测到的短语在识别引擎的语音缓冲区中的位置。Returns the location of a detected phrase within a recognition engine's speech buffer.

示例

下面的示例为SpeechRecognizer.SpeechDetectedSpeechRecognitionEngine.SpeechDetected事件创建了一个处理程序。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);  
  };
