speechClient.recognize() giving empty array as response?

[svsh227]

Using google-cloud/speech module my code is running fine and not producing any error, my mp3 file is also ok ( I have tested with multiple .mp3 files ). But is gives the response with empty array every times.

Can anyone please suggest me why is is happening ?

my code is:

// Imports the Google Cloud client library
const Speech = require('@google-cloud/speech');
process.env.GOOGLE_APPLICATION_CREDENTIALS = './speech-368abcdefghi.json'  

// Your Google Cloud Platform project ID
const projectId = 'engaged-talon-123456';

// Instantiates a client
const speechClient = Speech({
  projectId: projectId
});

// The name of the audio file to transcribe
const fileName = './5sec.mp3';

// The audio file's encoding, sample rate in hertz, and BCP-47 language code
const options = {
  encoding: 'LINEAR16',
  sampleRateHertz: 16000,
  languageCode: 'en-US'
};

// Detects speech in the audio file
speechClient.recognize(fileName, options)
  .then((results) => {
    console.log(results);
    // const transcription = results[0];
    // console.log(`Transcription: ${transcription}`);
  })
  .catch((err) => {
    console.error('ERROR:', err);
  });

Result
[" '', { results: [] } ]

Could you try a different encoding? Perhaps the Speech API is unable to read the file?

Someone on https://groups.google.com/forum/#!forum/cloud-speech-discuss may be able to help you get the file encoded properly.
