English to Romanian speech translation API

Stream English (English) speech and get Romanian (Română) back in real time. One WebSocket, ISO codes en to ro, and ultra-low latency for voice agents and live apps.

Trusted by

Production-ready English to Romanian translation API

Real English 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.

English (Indo-European > Germanic > West Germanic) 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.

English and Romanian through a single stream

English 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: "en" and target_language: "ro". It runs on the same WebSocket and the same model, with no extra round trip.
