Latvian to Czech speech translation API

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

Trusted by

Production-ready Latvian to Czech translation API

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

Latvian (Indo-European > Baltic) and Czech (Indo-European > Slavic > West Slavic) 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.

Latvian and Czech through a single stream

Latvian to Czech translation is built on top of Soniox Speech-to-Text API. Every spoken word is transcribed, and Czech 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: "cs". It runs on the same WebSocket and the same model, with no extra round trip.
