Thai to German speech translation API

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

Trusted by

Production-ready Thai to German translation API

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

Thai (Kra-Dai > Tai) and German (Indo-European > Germanic > West Germanic) 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 German in Latin, so Soniox emits correctly scripted German text.

Thai and German through a single stream

Thai to German translation is built on top of Soniox Speech-to-Text API. Every spoken word is transcribed, and German 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: "de". It runs on the same WebSocket and the same model, with no extra round trip.
