Key Points

  • The article asks whether it’s possible to reconstruct audio codes for Voxtral’s text-to-speech system when the relevant encoder is missing but some audio is available.
  • It presents a practical guide to “voice cloning” by leveraging code reconstruction from existing audio, effectively enabling a form of TTS surgery.
  • The approach focuses on reversing or approximating parts of the TTS pipeline (encoder-related components) to recreate representations needed for synthesis.
  • It frames voice cloning as a workflow centered on audio-code recovery rather than relying on a complete, standard model stack.

Can we reconstruct audio codes if we have audio for the Voxtral text-to-speech model?
