Upload any video — a conversation, a vlog, a lecture. Train on how people actually sound, not textbook recordings.
Sound like a native speaker - in any language
ShadowingMaster trains your ears and your mouth using the shadowing technique. Upload any video, slow it down, shadow it - and improve your pronunciation the way natives actually speak.
The part of language learning that changes everything.
Most language courses teach you words and grammar first. Speaking and listening come later - if at all. ShadowingMaster flips that. You hear how a native speaker sounds, you imitate them exactly, and you improve your pronunciation before you even think about rules. Your ears learn the rhythm. Your mouth learns the shape. The rest follows naturally. The part of language learning that changes everything.
Built for the part of language learning nobody talks about.

Frequently asked questions
What is shadowing?

What is shadowing?

Shadowing is a language-learning technique in which you listen to a native speaker and repeat what they say in real time-matching their rhythm, speed, and pronunciation. It was developed by researchers in the 1950s and is used by professional interpreters worldwide. It trains the connection between your ears and your mouth - the part of language learning that textbooks can’t reach.
