Polish speech recognition for production voice apps
Polish is spoken by more than 45 million people in Poland and around the world. If your voice agent, dictation app, or meeting notetaker serves them, speech-to-text has to handle Polish the way people actually speak it: regional accents, speakers who switch to English mid-sentence, and names, numbers, and IDs that have to come out exactly right.
Soniox STT transcribes Polish with native-speaker accuracy in real time over a WebSocket or asynchronously from recorded files, through one multilingual API built for 60+ languages. It follows speakers into other languages, labels who said what, and returns timestamps. Transcription biasing toward Polish is available through the language hints option.
Polish native-speaker accuracy
Accurate Polish speech recognition across accents, dialects, and real-world conversational speech.

“We tried a dozen speech-to-text and translation services. Soniox is the best, so that's what we use.”
Automatically detect and switch languages with Polish
Soniox identifies the language automatically and follows changes between Polish and other languages live, even within the same sentence.
Get every character right in Polish
Names, phone numbers, addresses, IDs, serial numbers, and other structured information spoken in Polish are recognized precisely.
