Well, the Echo translates all spoken language (written is a source of debate still) and there are a lot (in raw numbers, at least, though probably very few as a percent of the population) of people with the Echo. This probably made the transition from beastmen speaking their native language to speaking Eorzean somewhat simpler as they would likely be useful in facilitating the teaching of languages and raising interest among beast tribes for learning Eorzean.
How do we suppose the beastmen speak Eorzean and those interacting with them aren't Echo users or are speaking the native languages of the beast tribes? Well, I'm basing that at least in part on the colonialism that Eorzeans have employed toward beast tribes, but also that beast tribes appear able to communicate with one another, per the Vath quests. And some beastmen do business in city-state controlled lands, meaning they'd need to communicate with a vast majority of Eorzeans.Â
So my supposition is that in the five years between 1.0 and ARR there was a major push to teach beastmen Eorzean, likely as an effort to 'civilize' them.
