Qwen3-tts
Qwen3-TTS is an open-source text-to-speech platform designed to convert text into natural, human-like speech. It combines a high-efficiency 12Hz tokenizer with a multi-codebook speech encoder to produce detailed, low-latency audio that preserves paralinguistic features such as breath, hesitation, and emotional nuance. The model targets developers, researchers, and creators who need high-quality synthesis, zero-shot voice cloning, and real-time streaming for interactive voice applications.
Built for flexibility and scale, Qwen3-TTS supports over 10 languages, offers a Python SDK and an OpenAI-compatible API (deployable via Docker), and is released under the Apache 2.0 license for broad commercial and research use.

High-efficiency 12Hz Tokenizer
A proprietary tokenizer operating at 12Hz that compresses speech into compact tokens, enabling faster processing of long-form audio while retaining high fidelity.
Multi-codebook Speech Encoder
Architecture that balances sample compression and detail retention to capture subtle paralinguistic signals and nuanced speech attributes.
Zero-shot Voice Cloning
Clone a speaker's voice with as little as a 3-second reference clip without additional training; preserves timbre, accent, and style.
Context-aware Prosody
Adjusts prosody, intonation, and rhythm based on semantic understanding of the text to deliver appropriate acoustic weight for questions, exclamations, or somber statements.
Multilingual & Code-switching Support
Native support for 10+ languages (including English, Mandarin Chinese, Japanese, Korean, French, and German) and the ability to handle code-switching.
Ultra-low Latency Streaming
Dual-track generation architecture that can begin streaming audio in as little as 97 milliseconds first-token latency for real-time conversational applications.
Granular Emotion & Style Control
Control voice attributes via text prompts to instruct the model to whisper, shout, laugh, change speed, or express different emotional intensities.
Long-form Synthesis
Maintains consistency and flow across long passages, suitable for audiobooks, podcasts, and long-form narrations.
Open-source (Apache 2.0)
Released under the Apache 2.0 license, enabling modification, fine-tuning, and commercial use without restrictive proprietary constraints.
Developer Tooling
Python SDK, OpenAI-compatible API, and Docker deployment options to integrate into existing workflows and production environments.
Pricing
Qwen3-TTS is released under the Apache 2.0 open-source license, allowing free use, modification, and commercial distribution of the software. No commercial pricing details are provided on the page.

Getting Started
- 1 Step 1: Installation — Install the Qwen3-TTS package (pip) and ensure PyTorch is installed for optimal performance; the library manages most dependencies.
- 2 Step 2: Prepare Input & Prompt — Define the text to synthesize and optionally provide a short reference audio clip (e.g., 3 seconds) for zero-shot voice cloning. Add prompt instructions for desired emotion/style.
- 3 Step 3: Generate Audio — Call the generation function using the Python SDK or OpenAI-compatible API. For real-time needs, use the streaming API to receive audio chunks as they are generated.
- 4 Step 4: Deployment — Deploy to production using the provided Docker image to run an OpenAI-compatible API server or integrate the SDK into your application stack.
