Why do you still struggle to understand and speak after memorizing words?
Sound like a "robot"?
School teaches phonetics, not intonation. Your English gets chopped up and lacks the flow of native speakers.
Can't keep up with native speed?
Feel like natives "run words together"? That's because you don't know the rules of linking and reduction.
Bored of boring materials?
Textbook dialogues are dull. You want to learn from shows, TED talks, and your favorite YouTubers.
Who is TubeAccent for?
From self-learners to test takers—anyone who wants to sound more natural.
Whether you learn from shows, TED, or YouTubers, or you're prepping for speaking tests and presentations, TubeAccent's AI rhythm analysis helps you "see" stress and linking so your practice has direction and progress is visible.
