Shadow the movie lines you love. Loop the original audio, record yourself, and see your words and stress pattern scored — all on your device.
Practice English with the movie lines you already love — one line at a time.
Linespeak turns a movie you own into a shadowing coach. Import your own video file with its subtitles, pick a line, loop the original audio, say it back, and get scored on how close you came — words and stress pattern included.
HOW IT WORKS
1. Import a video you own (MP4 or MOV) together with its subtitles (SRT, VTT, or SMI), or just type a few lines.
2. Tap a line to loop the original audio for that exact moment, or hear a model voice (TTS).
3. Record yourself shadowing the line.
4. See your score: overall accuracy, word-by-word results, and your stress pattern next to the expected one.
MADE FOR FOCUSED PRACTICE
• Focused practice screen with a live waveform — turn your phone sideways for a two-column layout
• Loop any line as many times as you need; playback keeps going in the background
• Switch subtitle display between English and Korean when your file has both (SMI)
• Choose any installed English voice for the model speech, including premium voices downloaded in iOS
MYFAVORITE — YOUR OWN LINE COLLECTION
• Star the lines you want to keep. They are collected per movie with a review schedule (1 → 2 → 4 → 7 → 14 → 30 days)
• Landscape player: lines play like subtitles over the video, with a repeat count per line or for all lines
• Continue Learning takes you straight back to the last line you practiced
NO FILE YET? START ANYWAY
• Load Sample Movie — a short clip made for this app — to try the full flow in a minute
• Enter Lines Manually — type any lines and practice them with the model voice
GOOD TO KNOW
• Linespeak works with video files you own and can open in the Files app or Photos. It does not download movies and cannot import content from streaming apps or DRM-protected sources.
• MKV files can be imported for subtitle practice, but playback requires converting them to MP4 first.
• The app is in English and assumes you already read English comfortably — it is a speaking coach, not a beginner's course.
• Free, no account, no ads. Your recordings stay on your device.
