示例

以下示例演示了 可从 SpeakProgressEventArgs获取的信息。 StartParagraph请注意 、EndParagraph、 StartSentence和 EndSentence 方法通过向生成的 SSML 添加 <p>、</p>、<s> 和 </s> 标记对 的影响CharacterCount。 此外，输出中还有两个“30%”条目，每个单词一个条目用于说出此数字字符串 (百分之三十) 。 CharacterCount每个条目的 和 CharacterPosition 都相同，表示字符“30%。 然而，这些 AudioPosition 变化反映了 “30” 和 “百分比” 的 SpeechSynthesizer话语。

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.   
        synth.SetOutputToWaveFile(@"C:\test\weather.wav");  

        // Create a SoundPlayer instance to play the output audio file.  
        System.Media.SoundPlayer m_SoundPlayer =  
          new System.Media.SoundPlayer(@"C:\test\weather.wav");  

        // Build a prompt containing a paragraph and two sentences.  
        PromptBuilder builder = new PromptBuilder(  
          new System.Globalization.CultureInfo("en-US"));  
        builder.StartParagraph();  
        builder.StartSentence();  
        builder.AppendText(  
          "The weather forecast for today is partly cloudy with some sun breaks.");  
        builder.EndSentence();  
        builder.StartSentence();  
        builder.AppendText(  
          "Tonight's weather will be cloudy with a 30% chance of showers.");  
        builder.EndSentence();  
        builder.EndParagraph();  

        // Add a handler for the SpeakProgress event.  
        synth.SpeakProgress +=  
          new EventHandler<SpeakProgressEventArgs>(synth_SpeakProgress);  

        // Speak the prompt and play back the output file.  
        synth.Speak(builder);  
        m_SoundPlayer.Play();  
      }  

      Console.WriteLine();  
      Console.WriteLine("Press any key to exit...");  
      Console.ReadKey();  
    }  

    // Write each word and its character position to the console.  
    static void synth_SpeakProgress(object sender, SpeakProgressEventArgs e)  
    {  
      Console.WriteLine("CharPos: {0}   CharCount: {1}   AudioPos: {2}    \"{3}\"",  
        e.CharacterPosition, e.CharacterCount, e.AudioPosition, e.Text);  
    }  
  }  
}  

注解

当 对象引发 事件时SpeechSynthesizer，会创建 的SpeakProgress实例SpeakProgressEventArgs。 SpeechSynthesizer使用任何 Speak、SpeakAsync、 SpeakSsml或 SpeakSsmlAsync 方法，针对它在提示中说出的每个新单词引发此事件。

返回的数据基于代码生成的语音合成标记语言 (SSML) 。 为 CharacterCount 返回的值包括空格，以及代码生成的 SSML 标记的字符和内容。
