Understanding Greek OPUS files
Standard Modern Greek, based on the Demotic variety spoken in Greece, is the form most speech recognition models are trained on. Cypriot Greek differs noticeably in pronunciation and vocabulary, and regional accents from Crete and northern Greece can also vary from the Athens standard.

Frequently asked questions

Why won't my OPUS file play on my computer?
