This is an adapted and reorganized Meadow Mari-to-Russian translation data from AIRI's AI4TALK competition. It is intended for machine translation: each row contains Meadow Mari source text and a Russian translation. This task is text-based and does not include audio files. The original AI4TALK language code and recommended MDC source locale are both `mhr`. Meadow Mari, also known as Meadow-Eastern Mari, is a Uralic Mari language used mostly in European Russia and Mari El, with roughly 470,000 native speakers according to Wikipedia's current infobox.
