Stream Croatian (Hrvatski) speech and get Vietnamese (Tiếng Việt) back in real time. One WebSocket, ISO codes hr to vi, and ultra-low latency for voice agents and live apps.

Trusted by

Production-ready Croatian to Vietnamese translation API

Real Croatian 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.

Croatian (Indo-European > Slavic > South Slavic) 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.

Croatian and Vietnamese through a single stream

Croatian 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: "hr" and target_language: "vi". It runs on the same WebSocket and the same model, with no extra round trip.
