Living in SoCal, as far as I can tell, google maps generates some random numbers and then uses the result to decide whether it should use the Spanish or English pronunciation of roads with Spanish names.

In some cases it uses different pronunciations for two words in the same road name (I've heard "Calle Real" pronounced with "Calle" correct but "Real" as the English word "real"; other times it gets calle wrong and other times it gets them both right).
