Thai to Greek speech translation API

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

Trusted by teams building global voice products

Production-ready Thai to Greek translation API

Real Thai 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.

Thai (Kra-Dai > Tai) 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.

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

Thai and Greek through a single stream

Thai 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.

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