What is Violin?

Upload a video. Violin transcribes the speech, translates it, synthesizes a native-sounding voice-over in the target language, and remuxes it back into the video — fully aligned, with optional SRT subtitles.

Available as a CLI, a FastAPI web app, and a Claude Code skill.

Features:

  • 33 target languages with handpicked native-speaker voices for the 16 most-used ones (Cartesia Sonic 3 + ElevenLabs)
  • In-video Q&A — ask questions about any moment in the dubbed video; answers use nearby subtitles plus sampled frames
  • Natural-language voice picker — describe the voice you want, an LLM picks from the catalog
  • 6 style profiles (experimental) — standard / kids / academic / casual / storyteller / news
  • Pluggable stack — Together / OpenAI / ElevenLabs interchangeable for every stage, one YAML
