About Qwen3-TTS

Qwen3-TTS is an open-source series of text-to-speech models developed by the Qwen team at Alibaba Cloud. The repository documents released 0.6B and 1.7B models built on the Qwen3-TTS-Tokenizer-12Hz tokenizer, covering speech generation, voice design from free-form descriptions, voice cloning, and natural-language control over tone, speaking rate and emotional expression. A single model handles both streaming and non-streaming generation, with the project citing end-to-end synthesis latency as low as 97 ms.

The models cover ten languages — Chinese, English, Japanese, Korean, German, French, Russian, Portuguese, Spanish and Italian — along with multiple dialectal voice profiles. Usage paths listed in the repository include a Python package, a local web UI demo, the DashScope API and vLLM, together with fine-tuning material. Pricing is not stated on the homepage, and no safeguards or consent requirements for voice cloning are described there.
