蔚蓝。为什么默认微信的JavaScript STT-SDK只在PC上好用，在手机上却不行？

Question

Azure JavaScript-STT-SDK在PC上很好用，但在手机上就不行了。

const audioConfig = AudioConfig.fromDefaultMicrophoneInput()

//code
speech() {
      let that = this;
      const speechConfig = SpeechConfig.fromSubscription(
        "*******",
        "*******"
      );
      speechConfig.speechRecognitionLanguage = "zh-CN";
      const audioConfig = AudioConfig.fromDefaultMicrophoneInput();
      const recognizer = new SpeechRecognizer(speechConfig, audioConfig);
      recognizer.start;
      recognizer.recognizeOnceAsync(result => {
        switch (result.reason) {
          case ResultReason.RecognizedSpeech:
            console.log(`RECOGNIZED: Text=${result.text}`);
            that.inputMsg = result.text;
            console.log("    Intent not recognized.");
            break;
          case ResultReason.NoMatch:
            console.log("NOMATCH: Speech could not be recognized.");
            that.tts("没有听到您说话喔~");
            break;
          case ResultReason.Canceled:
            const cancellation = CancellationDetails.fromResult(result);
            console.log(`CANCELED: Reason=${cancellation.reason}`);
            if (cancellation.reason == CancellationReason.Error) {
              console.log(`CANCELED: ErrorCode=${cancellation.ErrorCode}`);
              console.log(
                `CANCELED: ErrorDetails=${cancellation.errorDetails}`
              );
              console.log("CANCELED: Did you update the subscription info?");
            }
            break;
        }
      });
    },

现在，要想在麦克风中使用它，你需要使用浏览器SDK，关于示例，你可以参考这个文档。从麦克风中识别语音.

Node: 当你用浏览器测试时，它不能在Safari浏览器上工作。 在Safari上，样本网页需要托管在Web服务器上；Safari不允许从本地文件加载的网站使用麦克风。
