French to Chinese speech translation API

Stream French (Français) speech and get Chinese (中文) back in real time. One WebSocket, ISO codes fr to zh, and ultra-low latency for voice agents and live apps.

Trusted by

Production-ready French to Chinese translation API

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

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

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

French and Chinese through a single stream

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

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