次の例では、 StateChangedイベントに関する情報を示します。The following example demonstrates the information that is available about the StateChanged event.

using System;  
using System.Speech.Synthesis;  
namespace SampleSynthesis  
  class Program  
    static void Main(string[] args)  
      // Initialize a new instance of the SpeechSynthesizer.  
      using (SpeechSynthesizer synth = new SpeechSynthesizer())  
        // Configure the audio output.   
        // Subscribe to StateChanged event.  
        synth.StateChanged += new EventHandler<StateChangedEventArgs>(synth_StateChanged);  
        // Subscribe to the SpeakProgress event.  
        synth.SpeakProgress += new EventHandler<SpeakProgressEventArgs>(synth_SpeakProgress);  
        // Speak the prompt.  
        synth.Speak("What is your favorite color?");  
        // Pause the SpeechSynthesizer object.  
        // Resume the SpeechSynthesizer object.  
      Console.WriteLine("\nPress any key to exit...");  
    // Write the state of the SpeechSynthesizer to the console.  
    static void synth_StateChanged(object sender, StateChangedEventArgs e)  
      Console.WriteLine("State: {0}    Previous State: {1}\n", e.State, e.PreviousState);  
    // Write the speak progress of the SpeechSynthesizer to the console.  
    static void synth_SpeakProgress(object sender, SpeakProgressEventArgs e)  


StateChangedEventArgsインスタンスは、 SpeechSynthesizerオブジェクトがイベントをStateChanged発生させたときに作成されます。An instance of StateChangedEventArgs is created when the SpeechSynthesizer object raises the StateChanged event. 新しいと以前SynthesizerStateのの値を取得するには、イベントのPreviousStateハンドラーのプロパティStateとプロパティにアクセスします。To obtain the values for the new and the previous SynthesizerState, access the State and PreviousState properties in the handler for the event.


PreviousState PreviousState PreviousState PreviousState

SpeechSynthesizer イベント前の StateChanged の状態を取得します。Gets the state of the SpeechSynthesizer before the StateChanged event.

State State State State

SpeechSynthesizer イベント前の StateChanged の状態を取得します。Gets the state of the SpeechSynthesizer before the StateChanged event.
