As he explained on his site:
Around 3 months into my backpacking trip, I was wondering around in Ukraine while trying to learn a few words. As hard as I tried, I would butcher the simplest of phrases such as "Good day" (Доброго дня). It was difficult to find Ukrainian vocals online, as it is not a widely spoken language, so I practiced by making a few voices recordings of Ukrainians I befriended.
Soon afterwards, I had the idea to post the recordings I've made online in an appealing fashion, and Localingual was born! My dream for this site is for it to become the Wikipedia of languages and dialects spoken around the world.
