Live Korean Translation for Streams — 실시간 자막

With StreamTranslate, adding Korean subtitles to your Twitch stream takes under 5 minutes. Sign up at streamtranslate.live and create a translation room. Set your source language to English and your target language to Korean. You will receive a browser source URL that you paste directly into OBS Studio or Streamlabs as a new layer in your scene. Once your OBS scene is active and you start streaming on Twitch, Korean Hangul subtitles appear live on top of your stream in real time with sub-100ms latency and perfect character rendering. No coding, no APIs to configure, no technical knowledge required beyond basic OBS use.

Yes — this is one of StreamTranslate's core advantages over generic translation services. The translation engine is specifically trained on Korean gaming vocabulary and esports terminology used in actual broadcast contexts. Common terms like 솔롡 (solo ranked), 정글 (jungle), 원떽 (ADC / marksman), 택 (top lane), 루드 (mid lane), 갑6‐‐‐‐‐‐‐‐‐47‐‐‐‐‐‐뱐 (ganking), 한타 (team fight), 컐리 (carry), and hundreds of other gaming-specific expressions are accurately recognized and handled. Generic engines trained on news articles or business text often mangle or entirely mistranslate these terms.

Absolutely. StreamTranslate supports KR to EN (Korean to English) translation, meaning Korean-speaking streamers on AfreecaTV, Twitch KR, or YouTube Live can have their speech automatically subtitled in English in real time. This is a powerful growth lever. Korean pro players and streamers in the LCK have massive latent English-speaking fan bases that cannot follow Korean audio. With KR to EN subtitles on screen, those fans can finally engage fully with content they have been watching on mute. The streamer does not need to change how they speak or add any extra effort — just enable the overlay and broadcast as normal.

StreamTranslate is trained on conversational Korean, which includes awareness of formal speech registers (존넽말) and informal or casual speech (반말). Streaming contexts typically use informal speech — streamers talking with their audience tend to use casual register with peers and formal register when addressing respected guests or sponsors. The system accurately captures the tone and meaning in both registers. Honorifics that convey relationship or social context are handled appropriately in the translated output, so English-speaking viewers receive a natural and contextually appropriate subtitle rather than a stiff literal translation that loses the relational nuance.

StreamTranslate's overlay works with any streaming setup that uses OBS Studio or compatible software such as Streamlabs OBS or XSplit. Since most AfreecaTV streamers, known as BJs (broadcast jockeys), broadcast via OBS-based software, you can integrate StreamTranslate as a browser source layer in your OBS scene. The Korean subtitles appear embedded in your stream output before it reaches AfreecaTV's servers, so viewers on the platform see the subtitles natively in the broadcast. For EN to KR translation, English-speaking streamers can reach AfreecaTV's Korean audience with Korean subtitles live on screen. For KR to EN, Korean BJs can simultaneously target an international Twitch or YouTube audience with English captions.
