# MOSS-TTS-Nano
Source <https://github.com/vllm-project/vllm-omni/tree/main/examples/offline_inference/moss_tts_nano>.
Single-stage offline TTS pipeline using the 0.1B MOSS-TTS-Nano AR LM and MOSS-Audio-Tokenizer-Nano codec. Outputs 48 kHz stereo WAV.
## Quick Start
```bash
python end2end.py --text "Hello, this is MOSS-TTS-Nano."
```
The first run downloads `OpenMOSS-Team/MOSS-TTS-Nano` and `OpenMOSS-Team/MOSS-Audio-Tokenizer-Nano` from Hugging Face.
## Usage
```
python end2end.py [OPTIONS]
Options:
--text TEXT Text to synthesize (default: "Hello, this is MOSS-TTS-Nano speaking.")
--voice VOICE Built-in voice preset (default: Junhao)
--mode MODE continuation (default) or voice_clone
--prompt-audio PATH Reference WAV/MP3 for custom voice cloning
--prompt-text TEXT Reference transcript (continuation mode)
--max-new-frames N Max AR frames, default 375 (~14 s audio)
--seed INT Random seed for reproducibility
--batch Run a built-in batch of diverse samples (ZH/EN)
--output-dir DIR Directory for WAV outputs (default: /tmp/moss_tts_nano_output)
--stage-config PATH Path to stage config YAML
```
## Examples
```bash
# Built-in Chinese voice
python end2end.py --text "你好，这是MOSS-TTS-Nano的语音合成演示。" --voice Junhao
# Built-in English voice
python end2end.py --text "Hello from MOSS-TTS-Nano." --voice Ava
# Batch synthesis
python end2end.py --batch --output-dir /tmp/batch_output
# Reproducible output
python end2end.py --text "Deterministic test." --seed 42
```
