A quick demo of a Google Translate–style web app that records voice, converts it to text, translates and speaks the result using the draft Web Speech API. It uses webkitSpeechRecognition for capture, SpeechSynthesis with SpeechSynthesisUtterance for TTS, and hits the known speechSynthesis.getVoices() async bug that needs polling. Works reliably in Chrome today, requires enabling a Firefox sandbox flag, and other browsers lack support for production use.
