How DubTab Works

DubTab operates as a browser extension that listens to audio from any open tab and translates it into the user's preferred language. Once installed, users can select their source and target languages, choose an AI voice, and start listening to dubbed audio while optionally viewing bilingual subtitles. The process is fully automated and happens in real time, ensuring minimal delay for live content such as streams and meetings.
