转换音频内存流

Question

  

您好我想将内存流转换为mp3，然后将其发送到   客户并发挥它：

这是我的asmx代码：

[WebMethod]
public byte[] StartSpeak(string Word)
{
    MemoryStream ms = new MemoryStream();
    using (System.Speech.Synthesis.SpeechSynthesizer synhesizer = new System.Speech.Synthesis.SpeechSynthesizer())
    {
        synhesizer.SelectVoiceByHints(System.Speech.Synthesis.VoiceGender.NotSet, System.Speech.Synthesis.VoiceAge.NotSet, 0, new System.Globalization.CultureInfo("en-US"));
        synhesizer.SetOutputToWaveStream(ms);
        synhesizer.Speak(Word);
    }
    return ms.ToArray();

}

感谢。
