Trusted by teams building global voice products
Production-ready German to Vietnamese translation API
Real German speech includes accents, regional dialects, code switching, and domain-specific vocabulary. Soniox recognizes it in a single model and streams Vietnamese while the speaker is still talking.
German (Indo-European > Germanic > West Germanic) and Vietnamese (Austroasiatic > Vietic) come from different language families, so word order and morphology differ. Soniox reorders meaning in-stream instead of word by word.
Soniox preserves formatting in the translated transcript, including names, numbers, addresses, IDs, and domain-specific terms.
A breakthrough in real-time German to Vietnamese translation
Translate before the sentence ends
Vietnamese meaning lands as German is spoken, not after the caption catches up.
Directional de to vi streaming
Set the source and target codes once. Both arrive in a single labeled token stream.
High quality Vietnamese output
Same model across every language, including historically underserved ones.
Native-speaker German STT accuracy
Accurate Vietnamese translation starts with accurate German recognition across accents and language switching.
Names, numbers, and domain terms
Preserved across the pair, including phone numbers, emails, and IDs.

}German and Vietnamese through a single stream
German to Vietnamese translation is built on top of Soniox Speech-to-Text API. Every spoken word is transcribed, and Vietnamese translation streams mid-sentence in the same labeled token stream.
Turn it on by adding a translation block with source_language: "de" and target_language: "vi". It runs on the same WebSocket and the same model, with no extra round trip.
