Speech recognition tuned to you and your game turns your voice into text, which is passed on to the BabelStreamer servers for translation
Every language on your plan is translated simultaneously — each viewer sees captions in the language they choose, not the one you speak. The servers deliver captions to the viewers in their chosen language with effective zero latency
Grow your livestream audience by going global — BabelStreamer translates your speech into captions in every language your viewers speak, automatically, with no extra work after setup, no towel required.
BabelStreamer's speech recognition and translation are tuned to specific games, language that engages viewers whatever language they speak. Speech recognition currently covers English, French, German, and Spanish.
BabelStreamer can be tuned to favour your specific choice of words and slang and is highly customisable to your own speech patterns. (Coming soon: speech recognition tuned to your own voice).
Viewers decide which language they want their captions in, and every available language is translated simultaneously. BabelStreamer currently translates to 13 languages, with more coming.
Captions arrive at about the same time as your stream, which means near zero added latency for your viewers.
