Qwen3-tts
Qwen3-TTS is an open-source text-to-speech model and audio synthesis platform designed to generate natural, human-like speech with fine-grained control over prosody, emotion, and style. It combines a high-efficiency 12Hz tokenizer and a multi-codebook speech encoder to compress and represent speech while preserving subtle paralinguistic cues such as breath, hesitation, and emotional intensity. Targeted at developers, researchers, and production teams, Qwen3-TTS supports zero-shot voice cloning from brief reference audio, multilingual synthesis across 10+ languages, and low-latency streaming suitable for real-time applications.

Zero-shot Voice Cloning
Clone a speaker's voice from as little as a 3-second reference clip; preserves timbre, accent, and nuances without additional training.
High-efficiency 12Hz Tokenizer
A proprietary tokenizer operating at 12Hz that compresses speech into compact tokens to enable long-form processing with high fidelity.
Context-aware Prosody
Adjusts prosody, intonation, and rhythm based on semantic context (questions, exclamations, somber statements) for more natural delivery.
Multilingual Synthesis & Code-switching
Native support for over 10 languages including English, Mandarin (and dialects), Japanese, Korean, French, and German; handles code-switching.
Ultra-low Latency Streaming
Dual-track generation architecture enabling streaming audio and first-token latency as low as 97 milliseconds for real-time conversational use.
Granular Emotion & Style Control
Control emotion and speaking style via text prompts to instruct whispering, shouting, laughing, pace, and other expressive attributes.
