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

Trusted by

Production-ready Slovenian to Croatian translation API

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

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

Soniox preserves formatting in the translated transcript, including names, numbers, addresses, IDs, and domain-specific terms.

Slovenian and Croatian through a single stream
