@Chenzeze777: Found an open-source voice synthesis model that I just had to share. 2 billion parameters, trained on 2 million hours of data, supports 30 languages plus 9 Chinese dialects—just input text and it synthesizes speech, including Sichuanese, Cantonese, and Northeastern dialects. The craziest part? Use natural language to describe a voice—like "young female, gentle and sweet"—and it creates a brand-new voice from scratch without needing any reference audio.
Summary
Introducing an open-source voice synthesis model with 2 billion parameters and 2 million hours of training. It supports 30 languages and 9 Chinese dialects, allows voice description via natural language, can clone voices from a 3-second recording, delivers 48kHz studio-quality audio, and is free for commercial use under the Apache-2.0 license.

I stumbled upon an open-source speech synthesis model, and I just had to share it.
With 2 billion parameters, trained on 2 million hours of data, it supports 30 languages plus 9 Chinese dialects—just input text and it synthesizes speech. It even covers Sichuanese, Cantonese, and Northeastern dialects.
The craziest part?
You can describe the voice in natural language—“young female, gentle and sweet”—and it will generate a completely new voice from scratch, without needing any reference audio.
Voice cloning is also impressive: give it a 3-second recording, then freely adjust emotion, speed, and expressiveness, outputting studio-quality 48 kHz audio.
Run it locally with just three lines of code. Licensed under Apache-2.0, free for commercial use.
If you make podcasts, short videos, or games, you’d be remiss not to bookmark this.

@lxfater: NetEase Youdao open-sourced ZiYue 4 model, within 27B parameters, SOTA in math and science. But what really interests me is its voice feature!!

Take your Chinese voice and use it to speak Japanese — it has a Chinese accent, you can tell it's a foreigner struggling...
