VOXO is Chrome-only and supports 31 subtitle target languages, with 28 recognition languages documented by its provider. Here are the best alternatives in 2026 — and why StreamTranslate tops the list.
VOXO.live launched in March 2026 with an important caveat: "This service only works on PC Chrome browser." It uses Chrome Web Speech API for free STT, limiting it to 31 subtitle target languages, with 28 recognition languages documented by its provider and Chrome lock-in.
RECOMMENDED StreamTranslate — streamtranslate.live
Choose your audio input and caption languages in Control, copy the complete overlay URL into an OBS or Streamlabs Browser Source, start the caption session intentionally, and check a short recording. Keep Control open when using browser-microphone capture. Start the video broadcast separately and stop caption capture for private breaks.

LocalVocal is a free, open-source OBS Studio plugin with local speech recognition and translation. It supports CPU processing; GPU acceleration is optional. Language coverage and performance depend on the model and translation provider. Optional cloud providers may charge separately. Caption timing and accuracy vary with audio, languages, connection, model and settings. We have not run a controlled head-to-head benchmark of these tools.

StreamTranslate’s official Twitch extension requires the broadcaster to install, activate and link it, supply audio and start the caption session. Each viewer can choose a caption language. It is separate from a viewer-only browser extension, typed-chat translation and Twitch’s native CC track. Browser Source captions are pixels in the broadcast video and do not give viewers a CC toggle.
