voicechat2 is an advanced AI voice chat infrastructure designed to deliver ultra-low latency voice-to-voice communication using WebSockets. This innovative solution operates entirely on a single high-end consumer GPU, making it a powerful and efficient choice for real-time voice interactions. With voice-to-voice latency as low as 300ms, voicechat2 outperforms many existing solutions, ensuring a seamless and responsive user experience.

Built on cutting-edge technologies, voicechat2 leverages models such as Whisper large-v2 (Q5), Llama 3 8B (Q4_K_M), and tts_models/en/vctk/vits (Coqui TTS default VITS models) to achieve its impressive performance. On an AMD RDNA3 card, the latency is in the 1-second range, while on a 4090 GPU, using Faster Whisper with faster-distil-whisper-large-v2, latency can be reduced to as low as 300ms. This makes voicechat2 ideal for applications requiring real-time voice processing and interaction.

Installation and setup are streamlined for ease of use, with detailed instructions provided for Ubuntu LTS systems. Users are guided through setting up ROCm or CUDA, and managing environments with conda or mamba. The process includes checking out the code, building whisper.cpp and llama.cpp, and installing necessary TTS models. Convenience scripts are also provided to help launch servers and manage connections.

voicechat2 stands out in the market for its fully local operation, ensuring data privacy and security. It eliminates the need for a unified voice codec, simplifying the infrastructure requirements. The product is versatile and can be used in various applications, from gaming and virtual meetings to customer service and educational platforms. Its low latency and high-performance capabilities make it a compelling choice for developers and businesses looking to integrate advanced voice chat functionalities into their products.

In summary, voicechat2 is a robust, efficient, and privacy-focused AI voice chat solution that offers unparalleled latency performance. Its ease of installation and setup, combined with its powerful features, make it an attractive option for anyone in need of high-quality, real-time voice communication.
