The Power of 125-Language Live Captions

English-only streams leave most of the internet's gaming audience locked out. Approximately 75% of internet users aren't native English speakers — and on platforms like Twitch and YouTube, non-English viewership is growing faster than English content.

StreamTranslate breaks that barrier. By captioning your stream in 125+ languages, you let Spanish-speaking viewers in Latin America follow your commentary, Japanese viewers understand your jokes, and Portuguese-speaking Brazilians — one of the fastest-growing gaming communities globally — feel like your stream was made for them.

The technical backbone is our industry-leading speech AI, a state-of-the-art speech recognition model that delivers captions with best-in-class accuracy even in challenging streaming environments: background music, game sound effects, multiple voices, and rapid speech patterns common in gaming.

Spanish & Portuguese

Latin America and Brazil represent over 400M potential gaming viewers. StreamTranslate reaches them instantly.

Japanese & Korean

Two of the highest-engagement gaming communities globally. Captions in their language dramatically increase watch time.

Arabic & European

French, German, Arabic, Italian — StreamTranslate covers all major European and MENA language markets.

Growing Your International Audience with Live Captions

Multilingual captions don't just help existing viewers — they actively attract new ones. Twitch and YouTube's discovery algorithms surface streams to viewers who watch similar content in their region. When your stream shows up with captions in Spanish, it gets recommended to Spanish-speaking viewers who'd never have found you otherwise.

Streamers who add multilingual captions via StreamTranslate consistently report viewership growth from unexpected geographic markets. A viewer who found your stream because of Spanish captions might clip a moment, share it in a Spanish Discord, and bring 50 more viewers your way.

Setup takes under 5 minutes. Follow the setup guide, add your OBS browser source, select your target language, and start reaching the world. See pricing — plans start at a price that makes sense even for small streamers investing in growth.
