Japanese to Basque speech translation API

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

Trusted by

Production-ready Japanese to Basque translation API

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

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

Japanese is written in CJK and Basque in Latin, so Soniox emits correctly scripted Basque text.

Japanese and Basque through a single stream

Japanese to Basque translation is built on top of Soniox Speech-to-Text API. Every spoken word is transcribed, and Basque translation streams mid-sentence in the same labeled token stream.

Turn it on by adding a translation block with source_language: "ja" and target_language: "eu". It runs on the same WebSocket and the same model, with no extra round trip.
