# qwen3-tts-flash

> The Qwen3-TTS-Flash is Tongyi's latest offline text-to-speech foundation model, featuring 17 expressive voices while enabling low-latency, high-stability audio synthesis. It supports multilingual and dialect outputs with consistent voice characteristics across languages. Trained on massive datasets, the system automatically adjusts vocal tones based on text semantics and demonstrates robust capabilities for synthesizing complex content.This model version is functionally equivalent to the snapshot model qwen3-tts-flash-2025-11-27.
