Dual-language streaming is the practice of broadcasting a live stream with captions in two languages simultaneously — typically the streamer's native language plus one target language. An English streamer might display English and Spanish captions at once, serving both audiences.
The streamer speaks normally. A tool like StreamTranslate transcribes the audio, then translates it into a second target language. Both captions (original + translated) are displayed simultaneously, usually stacked or side-by-side.
Dual-language captions serve both the native and foreign audience at once. They also help language learners and increase retention by 288% vs. English-only streams.
English + Spanish, English + Portuguese (Brazil), English + Japanese (VTubers), English + Korean. StreamTranslate Pro and Unlimited tiers support dual-language.
