Trusted by teams building global voice products
Production-ready Belarusian to Japanese translation API
Real Belarusian 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.
Belarusian (Indo-European > Slavic > East 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.
Belarusian is written in Cyrillic and Japanese in CJK, so Soniox emits correctly scripted Japanese text.
A breakthrough in real-time Belarusian to Japanese translation

High quality Japanese output
Same model across every language, including historically underserved ones.
Native-speaker Belarusian STT accuracy
Accurate Japanese translation starts with accurate Belarusian recognition across accents and language switching.
Names, numbers, and domain terms
Preserved across the pair, including phone numbers, emails, and IDs.

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