Trusted by

Production-ready Chinese to Spanish translation API

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

Chinese (Sino-Tibetan > Sinitic) and Spanish (Indo-European > Romance > Western Romance) come from different language families, so word order and morphology differ. Soniox reorders meaning in-stream instead of word by word.

Chinese is written in CJK and Spanish in Latin, so Soniox emits correctly scripted Spanish text.

Chinese and Spanish through a single stream

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

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