示例

下面的示例演示了从 SpeakProgressEventArgs中获取的信息。 请注意，StartParagraph通过将 EndSentence生成的 SSML，这些标记CharacterCount和方法如何影响它们。<><><><> 此外，“30%”的输出中有两个条目，每个单词都有一个条目来朗写这个数字字符串（30%） 。 每个 CharacterCount 条目的字符 CharacterPosition 相同，并表示字符“30%。 然而，反映 AudioPosition “三十”和“百分比” SpeechSynthesizer一词的讲话的变化。

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SpeakProgressEventArgs事件时SpeechSynthesizer，将创建一个实例SpeakProgress。 对于它使用任何、SpeechSynthesizerSpeakSpeakAsync或SpeakSsml方法在提示中说话的每个新单词，都会SpeakSsmlAsync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）。 返回的值包括 CharacterCount 空格和代码生成的 SSML 标记的字符和内容。
