AudioState 枚举

定义

命名空间:

System.Speech.Recognition

程序集:

System.Speech.dll

包:

System.Speech v8.0.0

Source:

AudioState.cs

音频输入到语音识别引擎包含可能状态列表。

public enum class AudioState

public enum AudioState

type AudioState = 

Public Enum AudioState

继承

Object

ValueType

Enum

AudioState

字段

Silence	1	接收沈默或非语音背景噪音。
Speech	2	接收语音输入。
Stopped	0	没有处理音频输入。

示例

以下示例演示一个事件处理程序，该事件处理程序处理语音识别器不断变化的音频状态。

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.  
}  

注解

可以使用 和 SpeechRecognizer.AudioState 属性获取语音识别引擎SpeechRecognitionEngine.AudioState的音频输入状态。 SpeechRecognitionEngine.AudioStateChanged当语音识别引擎的音频输入状态发生更改时，将引发 和 SpeechRecognizer.AudioStateChanged 事件。
