SpeechSynthesizer.SpeakAsyncCancelAll 메서드


모든 쿼리된 비동기 음성 합성 작업을 취소합니다.Cancels all queued, asynchronous, speech synthesis operations.

 void SpeakAsyncCancelAll();
public void SpeakAsyncCancelAll ();
member this.SpeakAsyncCancelAll : unit -> unit
Public Sub SpeakAsyncCancelAll ()


다음 예제에서는 표시를 사용 하는 SpeakAsyncCancelAll 새 프롬프트를 읽을 수 있도록 메시지의 비동기 말하기를 취소 합니다.The following example show a use of SpeakAsyncCancelAll to cancel the asynchronous speaking of a prompt, so that a new prompt can be spoken. SpeakCompleted 될 때 이벤트 발생을 SpeakAsync 작업이 취소 되었습니다.Note that the SpeakCompleted event fires when a SpeakAsync operation is cancelled.

using System;  
using System.Speech.Synthesis;  
using System.Threading;  
namespace SampleSynthesis  
  class Program  
    static void Main(string[] args)  
      // Initialize a new instance of the SpeechSynthesizer.  
      SpeechSynthesizer synth = new SpeechSynthesizer();  
      // Configure the audio output.   
      // Subscribe to the StateChanged event.  
      synth.StateChanged += new EventHandler<StateChangedEventArgs>(synth_StateChanged);  
      // Subscribe to the SpeakProgress event.  
      synth.SpeakProgress += new EventHandler<SpeakProgressEventArgs>(synth_SpeakProgress);  
      // Subscribe to the SpeakCompleted event.  
      synth.SpeakCompleted += new EventHandler<SpeakCompletedEventArgs>(synth_SpeakCompleted);  
      // Begin speaking a text string asynchronously.  
      synth.SpeakAsync("Speech is an effective and natural way for people to interact with applications, " +  
        "complementing or even replacing the use of mice, keyboards, controllers, and gestures.");  
      // Speak for four seconds.  
      // Cancel the SpeakAsync operation and wait one second.  
      // Speak a new text string.  
      synth.Speak("An urgent email message has arrived. Do you want to hear it?");  
      Console.WriteLine("Press any key to exit...");  
    // Write to the console when the SpeakAsync operation has been cancelled.  
    static void synth_SpeakCompleted(object sender, SpeakCompletedEventArgs e)  
      Console.WriteLine("\nThe SpeakAsync operation was cancelled!!");  
    // When it changes, write the state of the SpeechSynthesizer to the console.  
    static void synth_StateChanged(object sender, StateChangedEventArgs e)  
      Console.WriteLine("\nSynthesizer State: {0}    Previous State: {1}\n", e.State, e.PreviousState);  
    // Write the text being spoken by the SpeechSynthesizer to the console.  
    static void synth_SpeakProgress(object sender, SpeakProgressEventArgs e)
