Google Speech API not working in Node.js - node.js

Question

I am using Google Cloud Speech API in Node.js. When I send a local audio file it gives the result but when I try to send a live stream it gets stopped within a second. Can anyone help me with this?
I am using this file: recognize.js
this is the code when I pass the audio file to google speech API. here it is working fine.I am passing the audio file stored in fileName sending into google speech API
function sample() {
const projectId = 'project id';
let file = "conf.json" //google exported this for you
var speech = require('#google-cloud/speech')({
projectId: 'project id',
keyFilename: 'Speech to text-a5ff6058e586.json'
});
const fs = require('fs');
const fileName = 'C:/Users/nap1225/Downloads/audio-files/audio_001.wav';
// const fileName = 'C:/xampp/htdocs/SpeechWatson/public/audio/Us_English_Broadband_Sample_2.wav';
// const fileName = 'Sample 1.wav';
// const fileName = 'C:/Users/nap1225/Desktop/dolo.wav';
// Reads a local audio file and converts it to base64
const fileMp3 = fs.readFileSync(fileName);
const audioBytes = fileMp3.toString('base64');
const audio = {
content: audioBytes
};
const config = {
encoding: 'LINEAR16',
sampleRateHertz: 16000,
languageCode: 'en-US',
speechContexts: {
"phrases": ["refsum"]
}
};
const request = {
audio: audio,
config: config
};
speech.recognize(request)
.then((results) => {
const transcription = results[0].results[0].alternatives[0].transcript;
console.log(`Transcription: `, transcription);
})
.catch((err) => {
console.error('ERROR:', err);
});
}
sample();
2.here is the code I am sending stream audio.when I execute this code in, it is recording for 1 second and get stopped
function streamingMicRecognize () {
// [START speech_streaming_mic_recognize]
// Imports the Google Cloud client library
const record = require('node-record-lpcm16');
const projectId = 'project id';
let file="conf.json"//google exported this for you
const speech = require('#google-cloud/speech')({
projectId: 'project id',
keyFilename: 'Speech to text-a5ff6058e586.json'
});
// Instantiates a client
//const speech = Speech();
// The encoding of the audio file, e.g. 'LINEAR16'
const encoding = 'LINEAR16';
// The sample rate of the audio file in hertz, e.g. 16000
const sampleRateHertz = 16000;
// The BCP-47 language code to use, e.g. 'en-US'
const languageCode = 'en-US';
const request = {
config: {
encoding: encoding,
sampleRateHertz: sampleRateHertz,
languageCode: languageCode
},
interimResults: true, // If you want interim results, set this to true
singleUtterance: false
};
// Create a recognize stream
const recognizeStream = speech.streamingRecognize(request)
.on('error', console.error)
.on('data', (data) =>
process.stdout.write(
(data.results[0] && data.results[0].alternatives[0])
? `Transcription: ${data.results[0].alternatives[0].transcript}\n`
: `\n\nReached transcription time limit, press Ctrl+C\n`));
// Start recording and send the microphone input to the Speech API
record
.start({
sampleRateHertz: sampleRateHertz,
threshold: 20,
// Other options, see https://www.npmjs.com/package/node-record-lpcm16#options
verbose: false,
recordProgram: 'sox', // Try also "arecord" or "sox"
silence: '10.0',
device : 'plughw:0'
// device : settingsRecord.audio_input
})
.on('error', console.error)
.pipe(recognizeStream);
console.log('Listening, press Ctrl+C to stop.');
// [END speech_streaming_mic_recognize]
