我的工具：文本转音频文件

需求：

根据英语单词，语句生成wav文件。

根据文本，生成wav文件。

主要代码：

其实就是一个类，调用的是System.Speech.Synthesis.SpeechSynthesizer类，我们重新包装一下这个类，方便我们自己调用，代码如下：

/// <summary>
/// 文本转语音并保存wav和MP3文件
/// </summary>
public class MySpeech
{
    VoiceClass _setViceClass;
    public MySpeech(VoiceClass setViceClass)
    {
        _setViceClass = setViceClass;
    }
    private SpeechSynthesizer synth = null;
    /// <summary>
    /// 返回一个SpeechSynthesizer对象
    /// </summary>
    /// <returns></returns>
    private SpeechSynthesizer GetSpeechSynthesizerInstance()
    {
        if (synth == null)
        {
            synth = new SpeechSynthesizer();
        }
        return synth;
    }
    /// <summary>
    /// 开始朗读放在线程中
    /// </summary>
    /// <param name="VoiceObject"></param>
    private void RingVoice(object VoiceObject)
    {
        try
        {
            VoiceClass voiceClass = (VoiceClass)VoiceObject;
            synth = GetSpeechSynthesizerInstance();
            //synth.SelectVoice(voiceClass.VoiceName);
            if (_setViceClass.Rate > 0)
                synth.Rate = _setViceClass.Rate;
            if (_setViceClass.Volume > 0)
                synth.Volume = _setViceClass.Volume;

            synth.SpeakAsync(voiceClass.VoiceText);
        }
        catch (Exception er)
        {
            Console.WriteLine(er.ToString());
        }
    }
    /// <summary>
    /// 播放
    /// </summary>
    public void Play()
    {
        Thread thread = new Thread(RingVoice);
        thread.Start(_setViceClass);
    }
    public void SaveMp3()
    {
        try
        {
            synth = GetSpeechSynthesizerInstance();

            //synth.SelectVoice(_setViceClass.VoiceName);
            if (_setViceClass.Rate > 0)
                synth.Rate = _setViceClass.Rate;
            if (_setViceClass.Volume > 0)
                synth.Volume = _setViceClass.Volume;

            string str = System.AppDomain.CurrentDomain.BaseDirectory + "\\" + _setViceClass.VoiceText + ".wav";

            synth.SetOutputToWaveFile(str);
            synth.Speak(_setViceClass.VoiceText);
            synth.SetOutputToNull();
        }
        catch (Exception er)
        {
            Console.WriteLine(er.ToString());
        }
    }
}
