Trusted by teams building global voice products
Production-ready Spanish to Romanian translation API
Real Spanish speech includes accents, regional dialects, code switching, and domain-specific vocabulary. Soniox recognizes it in a single model and streams Romanian while the speaker is still talking.
Spanish (Indo-European > Romance > Western Romance) and Romanian (Indo-European > Romance > Eastern Romance) come from different language families, so word order and morphology differ. Soniox reorders meaning in-stream instead of word by word.
Soniox preserves formatting in the translated transcript, including names, numbers, addresses, IDs, and domain-specific terms.

}Spanish and Romanian through a single stream
Spanish to Romanian translation is built on top of Soniox Speech-to-Text API. Every spoken word is transcribed, and Romanian translation streams mid-sentence in the same labeled token stream.
Turn it on by adding a translation block with source_language: "es" and target_language: "ro". It runs on the same WebSocket and the same model, with no extra round trip.
