Latvian to Lithuanian speech translation API

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

Trusted by

Production-ready Latvian to Lithuanian translation API

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

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

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

Latvian and Lithuanian through a single stream

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

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