New: Soniox v5 Real-Time is here

English to Kannada speech translation API

Stream English (English) speech and get Kannada (ಕನ್ನಡ) back in real time. One WebSocket, ISO codes en to kn, and ultra-low latency for voice agents and live apps.

Trusted by teams building global voice products

Production-ready English to Kannada translation API

Real English speech includes accents, regional dialects, code switching, and domain-specific vocabulary. Soniox recognizes it in a single model and streams Kannada while the speaker is still talking.

English (Indo-European > Germanic > West Germanic) and Kannada (Dravidian > South Dravidian) come from different language families, so word order and morphology differ. Soniox reorders meaning in-stream instead of word by word.

English is written in Latin and Kannada in Kannada, so Soniox emits correctly scripted Kannada text.
