View history trafficWhat is Kyutai TTS
Kyutai TTS is a 1.6B parameter text-to-speech model developed by Kyutai, a French AI research laboratory, initially as an internal tool for their Moshi project before being released as open-source. The model represents a significant advancement in text-to-speech technology, particularly notable for its ability to begin audio generation with just the first few words of text, rather than requiring complete text input. It supports both English and French languages, and comes with hundreds of voices based on Expresso and VCTK datasets, making it highly versatile for various applications.
Key Features of Kyutai TTS
Kyutai TTS is a revolutionary open-source text-to-speech model with 1.6B parameters that supports real-time streaming of both text input and audio output. It features ultra-low latency (220ms), high accuracy with state-of-the-art word error rates, voice cloning capabilities, and support for English and French languages. The model uses a unique delayed streams modeling approach that allows it to begin audio generation before receiving complete text input, making it particularly suitable for LLM integration and interactive applications.
Real-time Text and Audio Streaming: First TTS model that streams both text input and audio output simultaneously, with only 220ms latency from first text token to first audio chunk
High Performance Voice Cloning: Can clone voices from 10-second audio samples with high speaker similarity (77.1% for English, 78.7% for French) while maintaining voice characteristics and quality
Production-Ready Architecture: Includes a robust Rust server supporting websockets and can handle up to 32 simultaneous requests on an L40S GPU with 350ms latency
Word-Level Timestamp Generation: Provides precise timing information for each word, enabling real-time subtitles and intelligent interruption handling
Use Cases of Kyutai TTS
AI Assistant Integration: Perfect for real-time voice AI assistants where low latency and natural conversation flow are crucial
Content Production: Suitable for generating long-form audio content like audiobooks or articles with consistent voice quality
Live Translation Services: Can be used for real-time translation applications where immediate voice output is required as text is being generated
Interactive Learning Platforms: Ideal for educational applications requiring real-time voice feedback and natural language interaction
Pros
Ultra-low latency with true real-time streaming capabilities
High accuracy with state-of-the-art word error rates
Robust production-ready implementation with good scalability
Cons
Limited language support (only English and French)
Voice cloning model not directly available to prevent misuse
Requires significant computational resources for optimal performance
How to Use Kyutai TTS
Install the Moshi server: Install the moshi-server crate via the command line. The server code can be found in the kyutai-labs/moshi repository
Configure the server: Use the config file from the repository. For TTS, use configs/config-tts.toml
Start the server: Launch the server using the command: moshi-server worker --config configs/config-tts.toml
Select a voice: Choose a voice from the provided repository of voices at huggingface.co/kyutai/tts-voices. The model uses 10-second audio samples for voice cloning
Stream text input: Start sending text to the model. The model will begin generating audio with just the first few words, without needing the complete text
Receive audio output: The model will generate audio with a latency of around 220ms from receiving the first text token. It also provides word-level timestamps for synchronization
For production deployment: Use the provided Rust server with Docker for production environments. The server provides streaming access over websockets and can handle multiple simultaneous connections
