That's what makes you sound natural instead of "textbook correct." Most apps stop at word matching. We compare your pitch contour to the speaker's frame by frame, so you can see where your intonation drifted. And we score every individual sound — so "th", "r", and short/long vowels stop blending into "close enough." This is the same technique simultaneous interpreters use to train their ear-to-mouth speed. Backed by 40+ years of language acquisition research (Krashen, Hamada). ▸ WHO IT'S FOR - Intermediate-to-advanced learners (B1+) who understand spoken English but still sound "non-native" - Test takers preparing for IELTS, TOEFL, OPI, PTE speaking sections — score per phoneme = score per IELTS criterion - Engineers, designers, PMs, and remote workers who present in English daily and want a 10-minute morning drill - ESL teachers building self-study plans around real, current content (not 1990s textbook dialogues) - Polyglots already using comprehensible input tools who want active speaking on top of listening practice ▸ WHICH VIDEOS WORK Any YouTube video with English subtitles — TED talks, podcasts, interviews, news, vlogs, tutorials, lectures, sitcoms. Manually-captioned videos give the cleanest phrase splits and the best pronunciation feedback. Auto-generated captions work but may miss punctuation. Music videos and clips under 30 seconds without subtitles will not split into phrases. ▸ PRIVACY-FIRST Your voice never leaves your computer on the free plan.
