For Some Reson the SpeechRecognition API does not work in replit, it only works in a new tab.

Code:

let sttRec = new webkitSpeechRecognition() || new SpeechRecognition(); -- Creates A New SpeechRecognition Object

...

sttRec.start(); -- Supposed to Start it But Never Dose Unless You Are In a New Tab

I know the Web Speech API is experimental but it should work in replit.
