Hello everyone, 17 is back with more workflow sharing!

Today, I’m introducing an open-source audio model that claims to outperform proprietary ones. It has a massive 4 billion parameters—small for text-to-image models, but compared to Qwen’s 1.3B TTS, it’s significantly larger. Here’s its open-source page; as you can see, it’s packed with details. The training data spans up to 10 million hours, and it natively supports ComfyUI.

It supports 83 languages, with Chinese, English, and Japanese delivering the best results in the top tier, followed by second and third tiers.

With over 1,500 emotion tags expressed in natural language descriptions, plus special sound effects like clearing throat, pauses, broadcast tones, and more, it’s already unmatched in the open-source space on these two fronts alone. In blind tests, it has also outperformed many proprietary audio models.

I’ve packaged the workflows for you. Below are the prompts I tested for multilingual, single-speaker voice cloning. Feel free to give them a try!
