Zen3 TTS variant for voice design: synthesize new speakers from natural-language descriptors (timbre, age, accent, affect) without reference audio.

Derived by fine-tuning Qwen/Qwen3-TTS-12Hz-1.7B-VoiceDesign (Alibaba Cloud, Apache-2.0).

This repository contains the model weights: model.safetensors (talker) plus a speech_tokenizer/ module (12 Hz codec), config and tokenizer files.

The model uses the qwen3_tts architecture and loads with transformers (>= 4.57). It is API-compatible with the upstream base — follow the inference recipe on the base model card Qwen/Qwen3-TTS-12Hz-1.7B-VoiceDesign.
