Getting started with Deeptranscript WebSocket streaming API

nodejs-example.js

const querystring = require('querystring');
const ws = require("ws");
const qs = querystring.stringify({{
    language: 'fr',
    sampleRate: sampleRate,  // WARN: must match recording configuration
    format: 's16le',   // WARN: must match recording configuration
    // expectedPhrases: ['can be a word or a short sentence'],
}})
const socket = new ws.WebSocket(`wss://:${{process.env.API_TOKEN}}@stream.deeptranscript.com/?${{qs}}`);
socket.on('open', () => {{
    console.log('socket opened');
    
    // Raw data is sent as is, no preprocessing needed
    inputStream.on('data', (bytes) => socket.send(bytes, {{ binary: true }});
    
    // IMPORTANT: send empty buffer to tell DT to terminate
    // transcription automatically close after 3s with no input data
    inputStream.on('end', () => socket.send(Buffer.from([]), {{ binary: true }}));
}});
socket.on('error', (err) => console.error(err));
socket.on('message', (data) => console.log('message received: %s', data));
socket.on('close', () => console.log('close event received => done'));
