Understand the world
At Soniox, our mission is simple: To understand people — through audio.
We believe that speech is the most natural and universal form of human communication. Yet for decades, voice technology has remained limited to a small number of languages, regions, and use cases. Our goal is to change that.
Founded in 2020, Soniox set out to build foundational AI for speech — technology that works for everyone, everywhere.
In 2021, we introduced the world's first unsupervised learning approach for speech recognition. This breakthrough redefined the field, allowing us to train speech models at massive scale without the limitations of labeled data. The result: record-setting accuracy and the foundation for a completely new generation of speech AI.
Today, Soniox provides the most advanced speech-to-text AI in the world.
One universal model that understands over 60 languages in real time — with high accuracy, speaker recognition, and support for naturally mixed-language conversations. For the first time, developers and businesses in every country can build voice-powered products that actually work in their own language.
Our goal is to make speech AI as universal, accessible, and powerful as the human voice itself. We're just getting started — and we can't wait to hear what you build with it.
