Japanese to Turkish speech translation API

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

Trusted by

Production-ready Japanese to Turkish translation API

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

Japanese (Japonic) and Turkish (Turkic > Oghuz) 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 Turkish in Latin, so Soniox emits correctly scripted Turkish text.

Japanese and Turkish through a single stream

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