Arabic to Japanese speech translation API

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

Trusted by

Production-ready Arabic to Japanese translation API

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

Arabic (Afro-Asiatic > Semitic > Central Semitic) and Japanese (Japonic) come from different language families, so word order and morphology differ. Soniox reorders meaning in-stream instead of word by word.

Arabic is written in Arabic and Japanese in CJK, so Soniox emits correctly scripted Japanese text. Right-to-left output is handled directly in the token stream.

Arabic and Japanese through a single stream

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

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