Dollim
돌림 · ドリム
Section-loop listening that trains your ear.
Listen without captions first. Mark the stretch you missed, slow it down if you need to, toggle subtitles on and off, and loop until it’s clear. Tap any phrase you don’t know to translate it. Works with YouTube and local files.
Highlights
Loop the part you missed
Listen without captions, mark the stretch you couldn’t catch, and loop just that A/B section until it’s clear.
Slow it down, keep the voice natural
Drop the speed to as low as 0.5× with the pitch preserved — no chipmunk effect, so even fast speech stays clear.
Tap any line to translate
Don’t know a phrase? Tap the caption to translate it, look it up, or save it — without ever leaving the video.
Shadow it, then compare by ear
Record your own take and play it against the original to hear the gap yourself. It compares by ear — it doesn’t score your pronunciation.

FAQ
- Is Dollim free?
- Yes, it’s free to use.
- Does it work with YouTube and my own files?
- Both. Open a YouTube link, or bring your own audio or video file.
- Can it slow audio down without distorting it?
- Yes — down to 0.5× with the pitch preserved, so slowed speech still sounds natural.
- Does it score my pronunciation?
- No. Dollim lets you record and compare your take with the original by ear; it doesn’t grade or correct pronunciation.
- Which languages does it support?
- Any language the video has captions for — Dollim works with whatever captions the source provides.
