Most simple example I could find for ongoing listening of microphone using the google cloud speech api.
// Imports the Google Cloud client library
const speech = require('@google-cloud/speech')
const record = require('node-record-lpcm16')
const client = new speech.SpeechClient({
// generated service key downloaded from cloud console
credentials: require('./admin-key.json')
