我正在 WP8 上实现简单的语音识别和合成（SSML）。当我在模拟器中测试应用程序时，一切都很好。但是当我在物理设备（HTC Windows Phone X8）上测试应用程序时，SSML 合成出现了一个问题。此 SSML 代码工作正常：

await synth.SpeakSsmlAsync(@"<speak version=""1.0""
                                 xmlns=""http://www.w3.org/2001/10/synthesis"" xml:lang=""en-US"">
                                 <voice gender=""female"">
                                     Volume level 100.
                                 </voice>
                             </speak>");

而这个 SSML：

await synth.SpeakSsmlAsync(@"<speak version=""1.0""
                                 xmlns=""http://www.w3.org/2001/10/synthesis"" xml:lang=""en-US"">
                                 <voice gender=""female"">
                                     <prosody volume=""100.0"">
                                         Volume level 100.
                                     </prosody>
                                 </voice>
                             </speak>");

抛出异常：

{System.FormatException:
      The text associated with this error code could not be found.
      at Windows.Phone.Speech.Synthesis.SpeechSynthesizer.SpeakSsmlAsync(String content)
      at PhoneApp1.MainPage.<voiceSynth_Click>d__9.MoveNext()}  System.Exception
{System.FormatException}

任何人都有任何想法，为什么<prosody>标签在设备上不起作用？

问题解决了！

<prosody volume=""100.0""> doesn't work because the number is not integer.
<prosody volume=""100""> it should look like this
