Installing the client library

npm install asr-vietspeech

Using the client library

const ViSpeech = require('asr-vietspeech');
const fs = require('fs');

// The name of the audio file to trascript
const fileName = __dirname + '\\files\\audio.wav';`Filename ${fileName}`);

// Reads a local audio file and converts it to base64
const file = fs.createReadStream(fileName);

// The audio file's encoding, sample rate in hertz, timeout, maxSize, token
const config = {
    token: process.env.API_KEY, // set api key get from asr system 
    encoding: 'LINEAR16', // set encoding
    sampleRateHertz: 16000, // set rate Hz
    timeout: 10000, // 10 seconds
    maxSize: 51200 // 50 Mb
const asrViSpeech = new ViSpeech(config); => {`Response ${JSON.stringify(result)}`)
}).catch(err => {
    console.error('Api key invalid', err);


Samples are in the samples/ directory. The samples' has instructions for running the samples.

The ASR Vispeech Node.js Client API Reference documentation also contains samples.

Supported Node.js Versions

Our client libraries follow the Node.js release schedule. Libraries are compatible with all current active and maintenance versions of Node.js.

Client libraries targetting some end-of-life versions of Node.js are available, and can be installed via npm dist-tags. The dist-tags follow the naming convention legacy-(version).

Legacy Node.js versions are supported as a best effort:

  • Legacy versions will not be tested in continuous integration.
  • Some security patches may not be able to be backported.
  • Dependencies will not be kept up-to-date, and features will not be backported.


This library follows Semantic Versioning.

This library is considered to be General Availability (GA). This means it is stable; the code surface will not change in backwards-incompatible ways unless absolutely necessary (e.g. because of critical security issues) or with an extensive deprecation period. Issues and requests against GA libraries are addressed with the highest priority.
