Issue in using google speech API with Node.js - node.js

Question

I have used below code snippet for google speech to text recognition,
var speech = require('google-speech-api');
var opts = {
file: 'speech.mp3',
key: '<Google API Key>'
};
speech(opts, function (err, results) {
console.log(results);
// [{result: [{alternative: [{transcript: '...'}]}]}]
});
Then I tried to do
"npm install google-speech-api"
from command prompt. It's giving error.
Then, I did
"npm install googleapis"
and it succeeded.
I executed the Node.js script from command prompt "node myspeech.js"...it's throwing error as,
module.js:341
throw err;
^
Error: Cannot find module 'google-speech-api'

Answer 1

As you can see in your error logs:
npm ERR! code ENOGIT
npm ERR! not found: git npm
ERR! npm ERR! Failed using git.
npm ERR! This is most likely not a problem with npm itself.
npm ERR! Please check if you have git installed and in your PATH.
You need to have git installed on your system, and in your PATH.
For Windows, you can use git-bash, for Debian/Ubuntu, a simple sudo apt-get install git should do the tricks.

const projectId = 'yourGoogleProjectId';
let file="conf.json"//google exported this for you
var speech = require('#google-cloud/speech')({
projectId: projectId,
keyFilename: file
});
const fs = require('fs');
const fileName = 'yourMp3FilePath';
// 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: 'AMR_WB',
sampleRateHertz: 16000,
languageCode: 'en-US'
};
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);
});
