Yes! it is on-line. :)

Last time I checked

https://browserspeechsynthesis.onrender.com

language: Portuguese - Brazil

How it works

No requirements needed at the first place

Just open the /public/index.html file

OR

You can start the Socket.IO server with

yarn start or npm start

Apparentely it doesn't need internet connection to work after installation, it probably has built-in packages and libraries in the browser

Modules

• Synth (Probably built-in package in the browser)

Packages (socket server only)

• Socket.IO
• Express
• CORS
• Nodemon

Extra

I almost forgot. This project works in portuguese only but you can change the language where:

const language = 'pt-BR';

/public/script.js file
or you can just search for "language"

HAVE FUN!
