Tamil to Japanese speech translation API

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

Trusted by

Production-ready Tamil to Japanese translation API

Real Tamil 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.

Tamil (Dravidian > South Dravidian) and Japanese (Japonic) come from different language families, so word order and morphology differ. Soniox reorders meaning in-stream instead of word by word.

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

Tamil and Japanese through a single stream

Tamil 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: "ta" and target_language: "ja". It runs on the same WebSocket and the same model, with no extra round trip.
