Production-ready Slovak to Bulgarian translation API

Real Slovak 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.

Slovak (Indo-European > Slavic > West Slavic) and Bulgarian (Indo-European > Slavic > South Slavic) come from different language families, so word order and morphology differ. Soniox reorders meaning in-stream instead of word by word.

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

Real-time Slovak to Bulgarian translation

Soniox streams the Slovak transcript and the Bulgarian translation on the same connection, word by word, so meaning lands while the speaker is still talking.
