New: Soniox v5 Real-Time is here
Build with API

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 teams building global voice products

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.

A breakthrough in real-time Latvian to Czech translation

Translate before the sentence ends

Czech meaning lands as Latvian is spoken, not after the caption catches up.

Directional lv to cs streaming

Set the source and target codes once. Both arrive in a single labeled token stream.

High quality Czech output

Same model across every language, including historically underserved ones.

Native-speaker Latvian STT accuracy

Accurate Czech translation starts with accurate Latvian recognition across accents and language switching.

Names, numbers, and domain terms

Preserved across the pair, including phone numbers, emails, and IDs.

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.
