The practice loop
Every line of your media, three ways through it. 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. |

Features
- Interactive transcripts —
.srt / .vtt imports, YouTube captions, or AI transcription aligned line by line. Tap a line to seek; select a word to look it up. Per-line translations and IPA when you want them.
- Echo (shadow reading) — Line-bounded loops that pause and rewind at the end of the line, so you can drill it without breaking flow. Every take is kept.
- Pronunciation assessment — Azure speech scoring per take: overall, accuracy, completeness, fluency and prosody, with per-word detail and your pitch contour laid over the original's.
- Dictate — Every line's text becomes shape bars (
H); listen first, then hover or press-and-hold a line to peek.
- Lookup in context — Translation, a dictionary entry, and an AI explanation of what the phrase means in this scene, in 15 lookup languages.
- Spaced-repetition vocabulary — Three-button flashcards on an SM-2 schedule, several contexts per word, Anki CSV export on paid plans.
- Craft — Say or type something in your own language; Craft rewrites it the way a native speaker would, reads it aloud, and sends it to the player to shadow.
- YouTube — Paste a link and play, with captions fetched and rendered as an interactive transcript.
- Practice poster — Turn a take into a 9:16 poster (cover frame, the line, your score) and share it.
- Sync — Library, progress, recordings, vocabulary and settings follow your Enjoy account across devices.
