Build with API

Basque to Finnish speech translation API

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

Trusted by teams building global voice products

Production-ready Basque to Finnish translation API

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

Basque (Language isolate) and Finnish (Uralic > Finnic) come from different language families, so word order and morphology differ. Soniox reorders meaning in-stream instead of word by word.

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

A breakthrough in real-time Basque to Finnish translation

Finnish meaning lands as Basque is spoken, not after the caption catches up.

Directional eu to fi streaming

High quality Finnish output

Same model across every language, including historically underserved ones.

Native-speaker Basque STT accuracy

Accurate Finnish translation starts with accurate Basque recognition across accents and language switching.

Preserved across the pair, including phone numbers, emails, and IDs.

Basque and Finnish through a single stream

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