Build with API

Catalan to Greek speech translation API

Stream Catalan (Català) speech and get Greek (Ελληνικά) back in real time. One WebSocket, ISO codes ca to el, and ultra-low latency for voice agents and live apps.

Trusted by teams building global voice products

Production-ready Catalan to Greek translation API

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

Catalan (Indo-European > Romance > Western Romance) and Greek (Indo-European > Hellenic) come from different language families, so word order and morphology differ. Soniox reorders meaning in-stream instead of word by word.

Catalan is written in Latin and Greek in Greek, so Soniox emits correctly scripted Greek text.

Catalan and Greek through a single stream

Catalan to Greek translation is built on top of Soniox Speech-to-Text API. Every spoken word is transcribed, and Greek translation streams mid-sentence in the same labeled token stream.
