Since last time I updated here, we have added CozyVoice3 to the suite (the nice thing about it is that it is finnally an alternative to Chatterbox zero-shot VC - Voice Changer). And now I just added the new Qwen3-TTS!
The most interesting feature is by far the Voice Designer node. You can now finnally create your own AI voice. It lets you just type a description like “calm female voice with British accent” and it generates a voice for you. No audio sample needed. It’s useful when you don’t have a reference audio you like, or you don’t want to use a real person voice or you want to quickly prototype character voices. The best thing about our implementation is that if you give it a name, the node will save it as a character in your models/voices folder and the you can use it with literally all the other TTS Engines through the 🎭 Character Voices node.
The Qwen3 engine itself comes with three different model types: 1- CustomVoice has 9 preset speakers (Hardcoded) and it supports intructions to change and guide the voice emotion (base doesn’t unfortunantly) 2- VoiceDesign is the text-to-voice creation one we talked about 3- and Base that does traditional zero-shot cloning from audio samples. It supports 10 languages and has both 0.6B (for lower VRAM) and 1.7B (better quality) variants.
\very recently a ASR (*Automatic Speech Recognition) model has been released and I intedn to support it very soon with a new node for ASR which is something we are still missing in the suite Qwen/Qwen3-ASR-1.7B · Hugging Face
I also integrated it with the Step Audio EditX inline tags system, so you can add a second pass with other emotions and effects to the output.
Of course, as any new engine added, it comes with all our project features: character switching trough the text with tags, language switchin, PARAMETHERS switching, pause tags, caching generated segments, and of course Full SRT support with all the timing modes. Overall it’s a solid addition to the 10 TTS engines we now have in the suite.
Now that we’re at 10 engines, I decided to add some comparison tables for easy reference - one for language support across all engines and another for their special features. Makes it easier to pick the right engine for what you need.
