New: Soniox v5 Real-Time is here

Polish to Latvian speech translation API

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

Trusted by teams building global voice products

Production-ready Polish to Latvian translation API

Real Polish 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.

Polish (Indo-European > Slavic > West Slavic) and Latvian (Indo-European > Baltic) 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 Polish to Latvian translation

Translate before the sentence ends

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

Directional pl to lv streaming

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

High quality Latvian output

Same model across every language, including historically underserved ones.

Native-speaker Polish STT accuracy

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

Names, numbers, and domain terms

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

Polish and Latvian through a single stream

Polish 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: "pl" and target_language: "lv". It runs on the same WebSocket and the same model, with no extra round trip.
