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 teams building global voice products
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.
