The voice platform for the world
We believe speech is the most natural way people communicate. But most voice technology still works well only in a few languages, in a few markets, and under ideal conditions. That is not good enough for a world that speaks many languages, switches between them naturally, and increasingly expects software to understand voice in real time.
Soniox was founded to change that.
We build foundational voice AI that helps developers, businesses, and individuals understand and use speech across languages, accents, and environments. Today, Soniox provides speech-to-text, text-to-speech, and translation in one unified platform, built for real-time products and global deployment.
Our technology is designed for the hardest parts of voice AI: multilingual speech, mixed-language conversations, names, numbers, noisy audio, and low-latency interaction. With support for 60+ languages through one platform, Soniox makes it possible to build voice products that truly work worldwide.
Our mission is to help the world understand every conversation.
