pip install -U huggingface_hub
CLI Download
Download the full repository
huggingface-cli download Qwen/Qwen3-TTS-12Hz-1.7B-VoiceDesign
Download a single file to a local folder (e.g. config.json into ./dir)
huggingface-cli download Qwen/Qwen3-TTS-12Hz-1.7B-VoiceDesign config.json --local-dir ./dir
See the official docs for more CLI options

# 模型下载
from huggingface_hub import snapshot_download
model_dir = snapshot_download('Qwen/Qwen3-TTS-12Hz-1.7B-VoiceDesign')
Git Download
Make sure git-lfs is installed first
git lfs install
git clone https://huggingface.co/Qwen/Qwen3-TTS-12Hz-1.7B-VoiceDesign
To skip LFS large-file downloads, use:
GIT_LFS_SKIP_SMUDGE=1 git clone https://huggingface.co/Qwen/Qwen3-TTS-12Hz-1.7B-VoiceDesign
Model files are hosted on the Hugging Face Hub — download directly via HF CLI / SDK / Git, not through this site.
PyTorch / Transformers Usage
Install Transformers
pip install -U transformers torch
Load the model and run inference
from transformers import AutoModelForCausalLM, AutoTokenizer
model = AutoModelForCausalLM.from_pretrained('Qwen/Qwen3-TTS-12Hz-1.7B-VoiceDesign')
tokenizer = AutoTokenizer.from_pretrained('Qwen/Qwen3-TTS-12Hz-1.7B-VoiceDesign')
Model Download
We recommend downloading the model via the ModelScope CLI or SDK.
Guidance:Before downloading, install ModelScope with:
pip install modelscope
CLI Download
Download the full repository
modelscope download --model Qwen/Qwen3-TTS-12Hz-1.7B-VoiceDesign
Download a single file to a local folder (e.g. README.md into ./dir)
modelscope download --model Qwen/Qwen3-TTS-12Hz-1.7B-VoiceDesign README.md --local_dir ./dir

We release Qwen3-TTS, a series of powerful speech generation models developed by Qwen, offering comprehensive support for voice cloning, voice design, ultra-high-quality human-like speech generation, and natural language-based voice control.
Overview
Qwen3-TTS covers 10 major languages (Chinese, English, Japanese, Korean, German, French, Russian, Portuguese, Spanish, and Italian) as well as multiple dialectal voice profiles. Key features:- Powerful Speech Representation: Powered by the self-developed Qwen3-TTS-Tokenizer-12Hz, it achieves efficient acoustic compression and high-dimensional semantic modeling.
- Universal End-to-End Architecture: Utilizing a discrete multi-codebook LM architecture to bypass traditional information bottlenecks.
- Extreme Low-Latency Streaming Generation: Supports streaming generation with end-to-end synthesis latency as low as 97ms.
- Intelligent Voice Control: Supports speech generation driven by natural language instructions for flexible control over timbre, emotion, and prosody.
Quickstart
Environment Setup
Install the qwen-tts Python package from PyPI:
pip install -U qwen-ttsPython Package Usage
import torch
import soundfile as sf
from qwen_tts import Qwen3TTSModel
Load the model
model = Qwen3TTSModel.from_pretrained(
"Qwen/Qwen3-TTS-12Hz-1.7B-CustomVoice",
device_map="cuda:0",
dtype=torch.bfloat16,
attn_implementation="flash_attention_2",
)
Custom Voice Generation
wavs, sr = model.generate_custom_voice(
text="其实我真的有发现,我是一个特别善于观察别人情绪的人。",
language="Chinese",
speaker="Vivian",
instruct="用特别愤怒的语气说",
)
sf.write("output.wav", wavs[0], sr)Evaluation
Zero-shot speech generation on the Seed-TTS test set (Word Error Rate (WER, ↓)):
| Model | test-zh | test-en |
|---|---|---|
| Qwen3-TTS-12Hz-1.7B-Base | 0.77 | 1.24 |
