Examples

The following example is part of a Windows Forms application that writes the information returned by the PhonemeReached event to a text box. The phonemes are characters from the International Phonetic Alphabet (IPA).

using System;  
using System.Collections.Generic;  
using System.ComponentModel;  
using System.Data;  
using System.Drawing;  
using System.Linq;  
using System.Text;  
using System.Windows.Forms;  
using System.Speech.Synthesis;  

namespace PhonemeReached  
{  
  public partial class Form1 : Form  
  {  

    public Form1()  
    {  
      InitializeComponent();  
      textBox1.Text = "";  
    }  

    public void button1_Click(object sender, EventArgs e)  
    {  
      // Initialize a new instance of the SpeechSynthesizer.  
      SpeechSynthesizer synth = new SpeechSynthesizer();  

      // Configure the audio output.   
      synth.SetOutputToDefaultAudioDevice();  

      // Register for the PhonemeReached event.  
      synth.PhonemeReached += new EventHandler<PhonemeReachedEventArgs>(synth_PhonemeReached);  

      // Speak the contents of a string.  
      synth.Speak("Theme");  
    }  

    // Write information about each phoneme as it is reached.  
    private void synth_PhonemeReached(object sender, PhonemeReachedEventArgs e)  
    {textBox1.AppendText(string.Format(  

        "  Phoneme reached summary:" + Environment.NewLine +  
        "    Phoneme:                 {0}" + Environment.NewLine +    
        "    Audio Position:         {1} mSec" + Environment.NewLine +  
        "    Duration:                  {2} mSec" + Environment.NewLine +  
        "    Emphasis:                {3}" + Environment.NewLine +  
        "    Next Phoneme:         {4}" + Environment.NewLine + Environment.NewLine,   
        e.Phoneme,  
        e.AudioPosition,  
        e.Duration,  
        e.Emphasis,  
        e.NextPhoneme));  
    }  
  }  
}
