Croatian to Bulgarian speech translation API

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

Trusted by

Production-ready Croatian to Bulgarian translation API

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

Croatian and Bulgarian both belong to the Indo-European > Slavic > South Slavic family, so cognates and shared structure carry over cleanly into the translated Bulgarian output.

Croatian is written in Latin and Bulgarian in Cyrillic, so Soniox emits correctly scripted Bulgarian text.

Croatian and Bulgarian through a single stream

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