How to watch a Korean livestream without speaking Korean

• Charge the device. Live captioning plus video is not a light workload.
• Use headphones if you are in a noisy room, or plan to use Around Me mode if the sound is coming from a speaker.
• Open Echo once beforehand and grant the microphone and Screen Broadcast permissions, so you are not tapping through prompts while the live starts.

1. 1

   Choose your mode

   Audio for a stream you are listening to, Screen for text on your display, Around Me for sound in the room.

2. 2

   Set the language pair

   Korean as the source, then English, 简体中文 or 繁體中文 as your reading language. Traditional and Simplified are separate targets, not one Chinese option.

3. 3

   Turn on the floating overlay

   The picture-in-picture window keeps captions on top once you switch back to the stream. This requires a physical device — it does not run in the Simulator.

Live translation is fast but not instantaneous — captions land a beat behind the speech, the way broadcast subtitles do. Overlapping voices, heavy background music and shouting all reduce accuracy, which is a limitation of speech recognition rather than of translation.

What Echo does guarantee is that idol names, group names and fandom vocabulary stay intact, because they are handled by a glossary rather than left to the model.

The free tier includes 5 minutes of translation every day with all features and no account. That covers a Bubble check or a teaser. For a full live, Echo Plus Weekly starts with a 3-day free trial, and the Day Pass gives you 90 minutes valid for 24 hours as a one-time purchase.
