Croatian to English speech translation API

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

Trusted by

Production-ready Croatian to English translation API

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

Croatian (Indo-European > Slavic > South Slavic) and English (Indo-European > Germanic > West Germanic) 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 English through a single stream

Croatian to English translation is built on top of Soniox Speech-to-Text API. Every spoken word is transcribed, and English 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: "en". It runs on the same WebSocket and the same model, with no extra round trip.
