Unmatched accuracy in Basque and 60+ languages

Basque is spoken by over 750 thousand people worldwide — primarily in Spain, with speakers around the world. For years, Basque speech-to-text has fallen short, failing at fundamentals like accurate and reliable recognition, multiple languages, and alphanumerics. It converted Basque audio into words, but the words lacked meaning and context.

Soniox reimagined everything Basque speech-to-text got wrong. You can speak naturally, switch languages mid-sentence, spell out codes and names, or ask for instant Basque translation, all in real-time. Soniox doesn’t just transcribe Basque speech – it understands it.

Basque native-speaker accuracy

Accurate Basque speech recognition across accents, dialects, and real-world conversational speech.
