Sada
Sada is a free browser tool for practising spoken English by shadowing captioned YouTube videos. How it works: open a video, listen to one short line, record yourself repeating it, and play your take back beside the original. Repeat the line until your rhythm, stress and pauses sound closer to the speaker. Word matching shows which words were recognised, so you can spot the ones that got lost. It does not grade individual speech sounds. What you can practise with: any YouTube video that has captions, or a curated library of caption-verified talks (TED and similar) sorted by level (B1, B2, advanced) and accent (American, British). Privacy: speech recognition runs in your browser and your recordings stay on your device. There is no account, no card and no extension to install. The interface is available in English and Arabic. Sada is free, with no paid tier.
