How to watch a Korean livestream in Chinese
Most Korean livestreams have no Chinese subtitles, and fan translations arrive hours later. Echo captions the stream into 繁體中文 or 简体中文 while it is still running, on your iPhone, with the original Korean shown alongside.
How do I get Traditional or Simplified Chinese subtitles on a Korean livestream?
Use Echo's Audio mode on an iPhone or iPad running iOS 26+. Select Korean as the source and 繁體中文 or 简体中文 as the target, start Screen Broadcast and turn on the floating overlay before returning to the livestream. For written messages instead of speech, choose Screen mode.
Traditional and Simplified Chinese are separate translation targets. Test with the 5 free minutes per day: app audio must be capturable and cloud translation needs an internet connection. The K-pop glossary helps recognize names and fandom terms, but does not guarantee correct captions.
Set it up once
- 1
Choose Audio mode
Audio mode captures the audio of another app through iOS Screen Broadcast — the right mode for a live playing on the same phone.
- 2
Set Korean → 繁體中文 or 简体中文
Echo keeps Traditional and Simplified separate, so you get the script you actually read rather than a converted approximation.
- 3
Enable the floating overlay
The picture-in-picture caption window stays above Weverse, YouTube or Bubble while the stream plays full screen.
Traditional and Simplified are not the same setting
Echo treats 繁體中文 and 简体中文 as separate targets rather than converting one into the other after the fact. Choose the one you read; you can change it between streams without restarting the broadcast.
Idol and group names stay intact
Generic translators re-romanise Korean names on the fly, which is how a group name turns into something unrecognisable mid-sentence. Echo pins roughly 770 K-pop terms — official idol names, group names and fandom vocabulary — so they survive the trip into Chinese.
What it costs
The free tier gives 5 minutes of translation a day with no account. A full live usually needs more: Echo Plus starts at a weekly plan with a 3-day free trial, and a one-time Day Pass gives 90 minutes valid for 24 hours with no subscription and no auto-renew. Prices are set per territory, so the App Store shows your local amount before you buy.
Also useful off-stream
- Screen mode for Bubble messages, fan-cafe posts and Weverse comments.
- Around Me for concerts, fan meetings and travel in Korea.
- Local translation history you can scroll back through after the live, and delete in one tap.
