The best of practice apps and YouTube
Shadowing apps
They score you, but only on their own material — and lessons you don't care about don't stick.
YouTube
Endless videos you actually want to watch, but rewinding is manual and nobody tells you if you sound right.
LingoFlash turns the YouTube videos you choose into shadowing practice and scores your pronunciation sentence by sentence.
Everything shadowing needs, in one player
AI pronunciation scores
Every sentence you say is scored out of 100, with words colour-coded and the sounds that were off spelled out.
Record and compare
Hear yourself right after the original and catch where you drift.
Word-by-word AI subtitles
Speech recognition times every word, so the one being spoken lights up as you follow along.
Sentence loops and auto shadowing
Listen, repeat, get scored, move on — line by line, hands-free.
Tap to look up, in your language
Tap any word for its meaning; select a phrase and AI explains how it's used — in your native language.

FAQ
What is shadowing?
Shadowing means listening to native speech and repeating it right after, like a shadow. It started as interpreter training and works on listening, pronunciation and the rhythm of English at the same time.
Which videos can I practise with?
Any English video on YouTube (TikTok works too) — paste the link. Even without captions, AI listens to the audio and builds word-timed subtitles, translated into your language. There are also 30 ready-to-go starter videos.
How detailed is the AI pronunciation score?
Every sentence gets an overall score out of 100 plus accuracy, fluency, completeness and rhythm. Words are colour-coded, and you can see which sounds were off (like /r/ vs /l/ or /θ/) and replay just that word from the original.
Which languages are translations in?
Subtitle translations, word meanings and AI explanations come in your native language: Simplified or Traditional Chinese, Japanese, Korean, Spanish or French — or plain English.
What's free?
Signing up is free, with 10 AI pronunciation scores a day and 60 minutes of AI subtitles a month. Pro ($6.99/month or $59.99/year) gives 100 scores a day and 600 minutes a month.
Do I need to download an app?
No. It runs in your phone or computer browser, and you can add it to your home screen to open it like an app.
