AudioState

欄位

Silence	1	接收靜音或非語音背景雜音。
Speech	2	接收語音輸入。
Stopped	0	未處理音訊輸入。

範例

下列範例示範事件處理常式，可處理語音辨識器變更的音訊狀態。

private SpeechRecognitionEngine sre;  

// Initializes the speech recognition engine.  
private void Initialize()  
{  
  sre = new SpeechRecognitionEngine();  

  // Add a handler for the AudioStateChanged event.  
  sre.AudioStateChanged += new EventHandler<AudioStateChangedEventArgs>(sre_AudioStateChanged);  

  // Add other initialization code here.  
}  

  // Handle the AudioStateChanged event.  
  void sre_AudioStateChanged(object sender, AudioStateChangedEventArgs e)  
{  
  AudioState newState = e.AudioState;  

  // Handle event here.  
}  

備註

您可以使用 和 SpeechRecognizer.AudioState 屬性，取得語音辨識引擎 SpeechRecognitionEngine.AudioState 的音訊輸入狀態。 SpeechRecognitionEngine.AudioStateChanged當語音辨識引擎的音訊輸入狀態變更時，就會引發 和 SpeechRecognizer.AudioStateChanged 事件。
