範例

以下範例展示了從 SpeakProgressEventArgs中可獲得的資訊。 請注意 、 StartParagraph、 EndParagraph和 StartSentence 方法如何EndSentence透過在生成的 SSML 中加入 >、>、> 和 > 標籤來影響 。 此外，輸出中「30%」有兩個項目，分別代表每個說出此數字字串的詞（30%）。 CharacterCount和 CharacterPosition 對每個條目相同，代表字元「30%。 然而， AudioPosition 為了反映「三十」和「百分比」這兩個詞的發音，這些變化會被 SpeechSynthesizer。

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);
    }
  }
}

備註

當SpeakProgressEventArgs物件提出事件時SpeechSynthesizer，會產生一個SpeakProgress實例。 該SpeechSynthesizer詞會根據提示詞中用任一Speak、SpeakAsyncSpeakSsml或SpeakSsmlAsync方法，每說出一個新詞就觸發此事件。

回傳的資料是基於程式碼產生的語音合成標記語言（SSML）。 回傳的 CharacterCount 值包含空格，以及由程式碼產生的 SSML 標籤的字元和內容。
