# qwen3-tts-flash-realtime

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