# qwen-audio-3.1-tts-plus

> Qwen-Audio-3.1-TTS-Plus is a high-quality, professional text-to-speech model for premium voices and content creation. It supports multiple languages and dialects, streaming speech synthesis, free-style instruction following, and fine-grained tags to control emotion, tone, persona, speaking rate, and volume. For voice cloning, it is more robust to noise and reverberation in reference audio, improving audio quality, clarity, and expressiveness. The Plus version emphasizes audio quality and resolution for professional scenarios such as brand voices, audio content creation, film and television dubbing, and character performance.
