Basque to Bulgarian speech translation API

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

Trusted by

Production-ready Basque to Bulgarian translation API

Real Basque 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.

Basque (Language isolate) 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.

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

Basque and Bulgarian through a single stream

Basque 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: "eu" and target_language: "bg". It runs on the same WebSocket and the same model, with no extra round trip.
