Slovak speech recognition for production voice apps
Slovak is spoken by more than 5.4 million people in Slovakia and around the world. If your voice agent, dictation app, or meeting notetaker serves them, speech-to-text has to handle Slovak 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 Slovak 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 Slovak is available through the language hints option.
Slovak native-speaker accuracy
Accurate Slovak 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.”
