Qwen3-TTS: Multilingual Speech Generation with Instruction-Based Voice Control

Qwen3-TTS: Multilingual Speech Generation with Instruction-Based Voice Control

Voice interfaces are evolving from basic audio output into expressive, real-time communication.

Qwen3-TTS is an end-to-end text-to-speech model on AIOZ AI, designed for real-time, multilingual speech generation with fine-grained voice control.

It combines streaming performance, instruction-based modulation, and multiple voice-generation workflows into a single model family.

About Qwen3-TTS

Qwen3-TTS supports speech generation across 10 major languages, including Chinese, Japanese, Korean, and Russian. The model enables users to control key aspects of speech through natural-language instructions, such as timbre, emotion, prosody, and rhythm.

Trained on over 5 million hours of speech data across these languages, Qwen3-TTS also supports real-time voice generation, 3-second voice cloning, and natural language voice control.

How Qwen3-TTS Works

Qwen3-TTS is built on a discrete multi-codebook language model architecture that enables end-to-end speech generation.

It is powered by the Qwen3-TTS-Tokenizer-12Hz, which:

  • Applies efficient acoustic compression at 12Hz
  • Supports high-dimensional semantic modeling

This design enables speech generation that balances efficiency and expressive control.

Real-Time Streaming Performance

Qwen3-TTS supports streaming speech generation with:

  • End-to-end latency as low as 97ms
  • A Dual-Track hybrid streaming architecture
  • Support for both streaming and non-streaming generation within a single model

These features enable real-time interaction for voice-driven applications.

Key Capabilities

Qwen3-TTS supports a range of voice generation workflows:

  • Instruction-driven speech generation
  • Voice design from text descriptions
  • Rapid voice cloning from ~3-second audio samples
  • Multiple timbre options across gender, age, and dialect combinations

These capabilities allow users to generate speech with controlled style and expression.

Model Variants

Qwen3-TTS is released as a model family with multiple configurations:

  • 0.6B and 1.7B parameter sizes
  • Variants including: Base, CustomVoice, and VoiceDesign

The 1.7B variants support instruction control, while the 0.6B variants are optimized for lightweight deployment.

All variants support streaming generation.

Ideal Use Cases

Qwen3-TTS can be applied across a wide range of voice-first applications, including:

  • Voice assistants: Real-time, multilingual, and streaming-ready.
  • Dubbing and localization: Speech generation across 10 languages with natural prosody.
  • Voice cloning: Rapid cloning from as little as 3 seconds of audio.
  • Audiobook and narration: Expressive, long-form speech with fine-grained style control.
  • Voice-enabled AI agents: Low-latency streaming for real-time conversational systems.

Its combination of streaming performance and controllable speech output makes it suitable for both interactive systems and content production workflows.
