Production-ready Dutch to Bulgarian translation API

Real Dutch 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.

Dutch (Indo-European > Germanic > West Germanic) 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.

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

Real-time Dutch to Bulgarian translation

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

Does Soniox handle Dutch dialects and accents?

Yes. Soniox handles Dutch dialects like Hollandic, Brabantian, and Flemish in a single model, so Bulgarian translation stays accurate across regions.
