MOSS TTS Local Transformer — MLX 8-bit

This repository contains an MLX-native int8 conversion of MOSS TTS Local Transformer for single-speaker text-to-speech on Apple Silicon.

Note This repo is a community mirror of the canonical MLX conversion maintained by AppAutomaton at appautomaton/openmoss-tts-local-mlx.

Variants

Model Details

• Developed by: AppAutomaton
• Shared by: mlx-community
• Original MLX repo: appautomaton/openmoss-tts-local-mlx
• Upstream model: OpenMOSS-Team/MOSS-TTS-Local-Transformer
• Task: single-speaker text-to-speech and voice cloning
• Runtime: MLX on Apple Silicon

How to Get Started

Command-line generation with mlx-speech:

Generate speech:

python scripts/generate_moss_local.py \
  --text "Hello, this is a test." \
  --output outputs/out.wav

Clone a voice:

python scripts/generate_moss_local.py \
  --mode clone \
  --text "This is a cloned voice." \
  --reference-audio reference.wav \
  --output outputs/clone.wav

Minimal Python usage:

from mlx_speech.generation import MossTTSLocalModel

model = MossTTSLocalModel.from_path("mlx-int8")

Notes

• This repo contains the quantized MLX runtime artifact only.
• The conversion keeps the original local TTS architecture and remaps weights explicitly for MLX inference.
• The default runtime path uses W8Abf16 mixed precision with global and local KV cache enabled.
• This mirror is a duplicated repo, not an automatically synchronized namespace mirror.
