Trusted by teams building global voice products
Production-ready Serbian to Japanese translation API
Real Serbian 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.
Serbian (Indo-European > Slavic > South Slavic) and Japanese (Japonic) come from different language families, so word order and morphology differ. Soniox reorders meaning in-stream instead of word by word.
Serbian is written in Cyrillic and Japanese in CJK, so Soniox emits correctly scripted Japanese text.
A breakthrough in real-time Serbian to Japanese translation

Japanese meaning lands as Serbian is spoken, not after the caption catches up.
Directional sr to ja streaming
Set the source and target codes once. Both arrive in a single labeled token stream.
High quality Japanese output
Same model across every language, including historically underserved ones.
Native-speaker Serbian STT accuracy
Accurate Japanese translation starts with accurate Serbian recognition across accents and language switching.
Names, numbers, and domain terms
Preserved across the pair, including phone numbers, emails, and IDs.

}Serbian and Japanese through a single stream
Serbian 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: "sr" and target_language: "ja". It runs on the same WebSocket and the same model, with no extra round trip.
