Maestra does file translation well. StreamTranslate is purpose-built for real-time live stream translation to 50+ languages — simultaneous, automatic, sub-500ms latency.
Start Free TrialSetup GuideThese are different technical problems. File translation takes an audio or video file, processes it at server speed, and produces translated output. There is no time pressure — quality can be refined over multiple passes and latency does not matter.
Live stream translation takes microphone audio, processes it in real time, produces translated captions, and delivers them to viewers — all within a window tight enough that captions feel synchronized with speech. Maestra is primarily a file translation tool that has added some live captioning capability. Live stream translation to 50+ languages simultaneously is not their core product.
StreamTranslate is a live stream translation tool from the ground up. Every decision — Deepgram Nova-2, sub-500ms latency targets, OBS Browser Source integration — exists to serve the live translation use case.
Your microphone audio is captured by the Browser Source and sent to StreamTranslate servers. Deepgram Nova-2 converts the audio to text with high accuracy. That text is then translated in parallel into multiple target languages using machine translation tuned for conversational content. Translated captions are delivered back to the Browser Source within the sub-500ms window. Viewers see captions in their language — determined automatically by browser language settings.
Europe: Spanish, Portuguese, French, German, Italian, Dutch, Polish, Russian, Swedish, Turkish. Asia: Japanese, Korean, Chinese Simplified, Chinese Traditional, Thai, Vietnamese, Indonesian, Hindi. Americas: Spanish LATAM, Portuguese BR, French CA. Middle East: Arabic, Hebrew, Persian. 50+ languages total, all available in real time.
