Greek to Thai speech translation API

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

Trusted by

Production-ready Greek to Thai translation API

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

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

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

Greek and Thai through a single stream

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

Turn it on by adding a translation block with source_language: "el" and target_language: "th". It runs on the same WebSocket and the same model, with no extra round trip.
