Rosetta Stone Solution

This puzzle was inspired by a trip I took to Russia. I noticed that a lot of popular American chains had locations in Russia, but they had translated their logos into Cyrillic. If you were dropped into this country and had never seen the Russian alphabet before, you could probably figure out how to read it just by looking at these signs and remembering their English names. The logos would act as a sort of modern Rosetta Stone, but for Russian instead of ancient Egyptian.

In this puzzle, you first have to identify the logos and then figure out the sounds represented by the glyphs. The glyphs form a substitution cipher, but for sounds instead of letters. For example, instead of writing the word "the" with three glyphs for "t", "h", and "e", you would write it with just two, one for "th" and another for "uh".

Logos: Subway, Best Buy, Burger King, Old Navy, Starbucks, Facebook, The Home Depot, Jif
