About the engine. The Quiet-Voice Engine is built on Qwen3-ASR — today's leading open-source ASR model — refined with our own engineering: fine-tuning for quiet-mode speech and near-field capture, near-field acoustic adaptation, latency and accuracy optimization, and cloud-side inference tuning. Baseline multilingual capability is inherited from Qwen3-ASR; quiet-mode performance reflects Razzhood's optimization. The comparison above was conducted internally by 3body Labs and has not been independently verified by any third-party benchmarking platform.

Founder's Letter
Founder & CEO
My father built a chain of shops that rewound burnt-out electric motors. I grew up around copper, machines, and money. Very young, I became a video game merchant, trading weapons and gear across platforms.
I later backed the AI startup behind Lenovo Smart Router as an angel investor. I sold part of my stake to Xunlei and JD.com. That was my first close look at AI reshaping consumer hardware.
Several months ago, a friend — an AI researcher who has worked at both Google and OpenAI — shared his vision for a new layer of human augmentation. He wants to communicate with his coding agents anytime, anywhere. That need inspired us to create Razzhood: a Quiet-Voice Engine designed for everyone.
