Open Source Voice Cloning & Design
Qwen has open-sourced Qwen3-TTS in a public repository, shipping high-fidelity text-to-speech alongside voice cloning and “describe-a-voice” style voice design controls.
The release packages capabilities that can be integrated directly into downstream apps and toolchains.
This puts upward pressure on the Fidelity dial.
- Lowers the cost and friction of producing near-human speech by making cloning and controllable voice design widely accessible.
- Widens distribution pathways: open-source availability speeds reuse in apps, agents, and localisation pipelines without bespoke vendor deals.
- Reduces the gap between “synthetic” and “indistinguishable” audio in everyday deployments, pushing expectations of realism upwards.
- Expands misuse surface area (e.g., scams and impersonation) by enabling high-quality voice generation with minimal barriers
“Qwen3-TTS is an open-source series of TTS models developed by the Qwen team at Alibaba Cloud, supporting stable, expressive, and streaming speech generation, free-form voice design, and vivid voice cloning.” - Qwen
