Lithuanian to Latvian speech translation API

Stream Lithuanian (Lietuvių) speech and get Latvian (Latviešu) back in real time. One WebSocket, ISO codes lt to lv, and ultra-low latency for voice agents and live apps.

Trusted by

Production-ready Lithuanian to Latvian translation API

Real Lithuanian speech includes accents, regional dialects, code switching, and domain-specific vocabulary. Soniox recognizes it in a single model and streams Latvian while the speaker is still talking.

Lithuanian and Latvian both belong to the Indo-European > Baltic family, so cognates and shared structure carry over cleanly into the translated Latvian output.

Soniox preserves formatting in the translated transcript, including names, numbers, addresses, IDs, and domain-specific terms.

Lithuanian and Latvian through a single stream

Lithuanian to Latvian translation is built on top of Soniox Speech-to-Text API. Every spoken word is transcribed, and Latvian translation streams mid-sentence in the same labeled token stream.

Turn it on by adding a translation block with source_language: "lt" and target_language: "lv". It runs on the same WebSocket and the same model, with no extra round trip.
