Code:个

const fs = require('fs');
const sdk = require("microsoft-cognitiveservices-speech-sdk");

const speechKey = "<speech-key>";
const speechRegion = "<speech-region>";

const speechConfig = sdk.SpeechConfig.fromSubscription(speechKey, speechRegion);
speechConfig.speechRecognitionLanguage = "en-US";
const audioConfig = sdk.AudioConfig.fromWavFileInput(fs.readFileSync("<audio-wav-file>"));
const speechRecognizer = new sdk.SpeechRecognizer(speechConfig, audioConfig);

async function inner() {
  return new Promise((resolve, reject) => {
    let response = "";

    speechRecognizer.recognizing = (s, e) => {
      if (e.result.reason === sdk.ResultReason.RecognizingSpeech) {
        console.log(`RECOGNIZING: Text=${e.result.text}`);
        response += e.result.text;
      }
    };

inner()
  .then((msg) => {
