Usage
# Install Hugging Face transformers
pip install transformers torch
# Load model with transformers
from transformers import AutoModel, AutoTokenizer
model = AutoModel.from_pretrained("Qwen/Qwen3-TTS-12Hz-0.6B-CustomVoice")
tokenizer = AutoTokenizer.from_pretrained("Qwen/Qwen3-TTS-12Hz-0.6B-CustomVoice")
Hugging Face Download
We recommend downloading the model via the Hugging Face CLI or Hub SDK.
Guidance:Before downloading, install huggingface_hub with:
pip install -U huggingface_hub
CLI Download
Download the full repository
huggingface-cli download Qwen/Qwen3-TTS-12Hz-0.6B-CustomVoice
Download a single file to a local folder (e.g. config.json into ./dir)

Qwen3-TTS-12Hz-0.6B-CustomVoice
Qwen3-TTS is a series of advanced multilingual, controllable, robust, and streaming text-to-speech models developed by the Qwen team.
This specific checkpoint is the 0.6B CustomVoice variant, based on the 12Hz tokenizer. It supports 9 premium timbres and allows for fine-grained style control over target voices via natural language instructions across 10 major languages.
- Paper: Qwen3-TTS Technical Report
- GitHub: QwenLM/Qwen3-TTS
- Demo: Hugging Face Spaces
Key Features
- Multilingual Synthesis: Supports Chinese, English, Japanese, Korean, German, French, Russian, Portuguese, Spanish, and Italian.
- Intelligent Control: Adapts tone, rhythm, and emotional expression based on natural language instructions (e.g., "Speak in a very happy tone").
- Low Latency: Optimized for streaming generation with the Qwen3-TTS-Tokenizer-12Hz, achieving end-to-end synthesis latency as low as 97ms.
Quickstart
To use Qwen3-TTS, you can install the qwen-tts package:
pip install -U qwen-ttsSample Usage
import torch
import soundfile as sf
from qwen_tts import Qwen3TTSModel
Load the model
model = Qwen3TTSModel.from_pretrained(
"Qwen/Qwen3-TTS-12Hz-0.6B-CustomVoice",
device_map="cuda:0",
dtype=torch.bfloat16,
attn_implementation="flash_attention_2",
)
Generate speech with specific instructions
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",
)
Save the generated audio
sf.write("output_custom_voice.wav", wavs[0], sr)Supported Speakers
For Qwen3-TTS-12Hz-0.6B-CustomVoice, the following speakers are supported. We recommend using each speaker’s native language for the best results:
