在 tensorflow js 中播放原始音频数据

Question

我有一个基于博客的使用 tensorflow.js 的音频分类器。

https://codelabs.developers.google.com/codelabs/tensorflowjs-audio-codelab/index.html?index=..%2F..index#0

我想在预测后播放识别器具有的原始音频（下面代码中的数据）。 如何播放音频？

  recognizer.listen(async ({spectrogram: {frameSize, data}}) => {
  const vals = normalize(data.subarray(-16 * NUM_FRAMES));
  const input = tf.tensor(vals, [1, ...INPUT_SHAPE]);
  const probs = model.predict(input);

  // want to play the sound here

  const predLabel = probs.argMax(1);
  console.log("predLabel : "+predLabel)
  tf.dispose([input, probs, predLabel]);
  
  }, {
  overlapFactor: 0.5,
  includeSpectrogram: true,
  invokeCallbackOnNoiseAndUnknown: true
 });
