# VibeVoice — MLX
|
| 21 |
+
|
| 22 |
+
VibeVoice converted and quantized for native MLX inference on Apple Silicon.
|
| 23 |
+
|
| 24 |
+
A hybrid LLM + diffusion architecture built for long-form speech and voice-conditioned generation. Works in greedy or sampled mode, and produces natural-sounding output at scale.

+
## How to Get Started
|
| 33 |
+
|
| 34 |
+
Via [mlx-speech](https://github.com/appautomaton/mlx-speech):
|
| 35 |
+
|
| 36 |
+
```bash
|
| 37 |
+
python scripts/generate_vibevoice.py \
|
| 38 |
+
--text "Hello from VibeVoice." \
|
| 39 |
+
--output outputs/vibevoice.wav
|
| 40 |
+
```
|
| 41 |
+
|
| 42 |
+
```python
|
| 43 |
+
from mlx_speech.generation import VibeVoiceModel
|
| 44 |
+
|
| 45 |
+
model = VibeVoiceModel.from_path("mlx-int8")
|
| 46 |
+
```
|
| 47 |
+
|
| 48 |
+
## Model Details
|
| 49 |
+
|
| 50 |
+
VibeVoice uses a 9B-parameter hybrid architecture combining a Qwen2 language model backbone with a continuous diffusion acoustic decoder. Converted to MLX with explicit weight remapping — no PyTorch at inference time.
