SoniTranslate

What it does

Feed it a video and it translates the speech, generates audio in the target language, and lines it up with the original timing, with separate voices per speaker if you want them. Runs from a browser UI locally or via the provided Colab notebook if you lack the GPU. Two error-prone steps stack here, so review before publishing — and never recreate a real person's voice speaking words they didn't say. The hosted demo Space was paused as of 2026-08-17. Apache-2.0.
