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.
Real-time Chinese to Spanish translation
Soniox streams the Chinese transcript and the Spanish translation on the same connection, word by word, so meaning lands while the speaker is still talking.
One-way translation
Translate live Chinese into Spanish. Everyone in the conversation sees the same translated stream.
Two-way Chinese and Spanish conversation
Each side speaks naturally and hears the other in their own language. Use it for live interpreters, bilingual voice agents, travel assistants, and customer support.
Chinese and Spanish through a single stream
Set the source and target codes once. Transcript and translation arrive interleaved on one labeled token stream, with no extra round trip.
