Definitely a LitRPG Isekai, with all the game mechanics. But not all that hardcore, either; when looking at the goblins he didn't have a stat screen come up.
Interesting take on the translation ability, being one-way; that's not standard at all in Isekai.
It appears to be treated as a software translation utility, receiving external input and providing him with the translation, but not being hooked up to external speakers to broadcast a translation of what he says.
Question: is that a design flaw, or is it that he just doesn't have external speakers? If the latter, as he has access to the game store, are speakers available for purchase? And, if so, how much of his funds would they require?
