Demo on https://alphacephei.com that recognize from a microphone doesn't work.

It says WebSocket URL is non-existent. To make it work we should use something like https://github.com/msqr1/Vosklet (alert: I'm the author). It loads models and recognize locally like vosk-browser, but it's faster and doesn't use deprecated features. It's also lighter, has more function and features than vosk-browser.
