KABURI-TTS

KABURI-TTS generates both speakers of a Japanese conversation together. It learns timing from LLM-jp-Zoom1 and can reproduce overlaps, pauses and short listener responses.

Research release

The current timing pipeline differs from the paper

The current version uses separate realizer and gap models. The paper's single timing predictor remains available through paper-mode and the paper-release-v1 code tag. Speaker reference audio is not included.KABURI-TTS official model card

Preserve the two speaker channels

Practical guidance. Use the channel separation when editing dialogue or studying overlapping speech. Mixing both channels too early would remove information that the model was designed to preserve.
