qwen-audio-3.1-tts-next

Qwen-Audio-3.1-TTS-Next is an AudioGen model designed for unified audio generation. Going beyond conventional TTS systems that focus solely on speech synthesis, it can generate complete audio content in a single pass from inputs such as text, timestamps, and reference audio, seamlessly combining speech, sound effects, ambient sounds, and more. The model supports a wide range of tasks, including multilingual TTS, single-speaker speech, multi-speaker dialogue, podcasts, cinematic soundscapes, ambient audio, and sound effects. Its key strengths include more natural and expressive speech, consistent voice identity, flexible timing control, and high-quality soundscape generation. These capabilities make it well suited for content creation, short-form video, podcasts, film and television production, game audio, and other professional audio creation scenarios.
