StreamTranslate

StreamTranslate is a live translation service designed to help streamers connect with audiences across language barriers. It turns spoken audio into real-time translated captions in 65 languages, with options for single or dual-language subtitles. Streamers can add captions to broadcasts through a browser source in tools such as OBS Studio, Streamlabs, Meld Studio, and other compatible software, or use supported mobile apps and RTMP workflows for IRL streaming. The service also offers an official Twitch extension that lets viewers choose their own caption language when a channel supplies audio.

Beyond live broadcasts, StreamTranslate provides video translation for VODs, clips, and recordings, with downloadable subtitles that users can customize. Its additional offerings include ClipLab and a free chat translator for viewers. Setup involves connecting a microphone or stream audio, selecting languages, and going live. A free plan includes three hours per month, while video translation is available on a pay-as-you-go basis without a subscription. StreamTranslate supports a range of desktop, cloud, and mobile streaming setups.
