The practice loop

Three ways through every line.

Listen until you hear every word, say it back until it sounds right, then hide the text and test your ears. Switch any time — the line stays where you are.

Listen

Every line in time with your media. Tap to seek, loop a line, slow it down, and read the translation and IPA when you need them.

Echo

Shadow one line at a time. Record over the original, replay both, compare the pitch, and get a score for every take.

Dictate

Hide the text. Words turn into shapes, so you listen first — then hover or hold a line to peek and check yourself.

Interactive transcripts

Your media, with every line in time.

Open an MP4 or an audio file, or paste a YouTube link. Import .srt / .vtt, use YouTube captions, or let AI transcribe and align it line by line.

Local files play locally — nothing is uploaded to watch
No subtitles? AI transcribes and aligns them
Translations under each line, cached on your device
IPA over every word when you want it

Enjoy Player on desktop: the transcript with the looped line, IPA over each word and the Chinese translation underneath

Pronunciation assessment

Feedback down to the sound you got wrong.

Every take is scored the moment you stop recording — overall, then accuracy, fluency, completeness and prosody, then every word. Tap a word to see which sound slipped.

Four dimensions, every word colour-coded

A scored take: overall 84, with accuracy, completeness, fluency and prosody bars and per-word scores

Lookup & vocabulary

Look it up in context. Keep it for good.

Select any word or phrase for a translation, a dictionary entry and an AI note on what it means in this scene. One tap saves it — with the line it came from — to a deck that comes back when you're about to forget.

Home: continue practising, today's goal and the community

Vocabulary: words due today, progress by status and every saved word with its context

Craft

Practise what you actually want to say.

Say or type something from your day in your own language. Craft rewrites it the way a native speaker would, reads it aloud, and drops it into the player so you can shadow it like any other line.
