# mlx-community/Irodori-TTS-500M-v3-8bit

Japanese TTS model converted to MLX 8-bit quantized format from [Aratako/Irodori-TTS-500M-v3](https://huggingface.co/Aratako/Irodori-TTS-500M-v3) using [mlx-audio v0.4.3](https://github.com/Blaizzy/mlx-audio).

## Features (v3)

- **Duration predictor**: automatically estimates output length — no need to specify 
- **Sway Sampling**: non-linear timestep schedule for better quality with fewer steps
- **Voice cloning**: optional  for speaker style transfer
- **Backward compatible**: v2 checkpoints continue to work
