选到语音名称

在ssml选一个语音，会生成到左边代码里，voice name=‘xxxxxx’

https://azure.microsoft.com/zh-cn/services/cognitive-services/text-to-speech/#features

一、直接上代码

方式一：直接调用

  <dependency>
      <groupId>com.microsoft.cognitiveservices.speech</groupId>
      <artifactId>client-sdk</artifactId>
      <version>1.12.1</version>
  </dependency>

@PostMapping("/text-to-url")
    @ApiOperation("地址识别")
    public Result getArea(String text) {
        SpeechConfig speechConfig = SpeechConfig.fromSubscription("你的apiKey", "eastasia");//key,地区
        speechConfig.setSpeechSynthesisLanguage("zh-CN");//语言
        speechConfig.setSpeechSynthesisVoiceName("zh-CN-XiaoxiaoNeural");//语言名称
     	 speechConfig.setSpeechSynthesisOutputFormat(SpeechSynthesisOutputFormat.Riff24Khz16BitMonoPcm);
        SpeechSynthesizer synthesizer = new SpeechSynthesizer(speechConfig, null);
        SpeechSynthesisResult result = synthesizer.SpeakText(text);
        AudioDataStream stream = AudioDataStream.fromResult(result);
        stream.saveToWavFile("D:/file.wav");//生成位置
        stream.close();
        return new Result();
    }

方式二：ssml（因为别人写过了，我这边就不写了，实测不好用，看了官方文档，写了方式一）
