Male; robotic, young voice (see D-0 from Rise of Skywalker movie for reference). Speech should sound as if you are translating for a Wookie speaking; meaning, the rhythym or cadence of the words spoken should not sound perfect. The thing I love about this part is that this elderly Wookie is wearing a translating modulator to communicate with others during a battle for his species freedom, and the voice of the translating modulator is quite the contrast to what you'd expect. Instead of an older voice to match the Wookie's age, we have this young, strangely optimistic voice translating his words for readers and listeners. I'm hoping this will create an oddly humorous experience. D-O from Rise of Skywalker is done with a younger voice, though the droid is shy and a bit fearful. I'd like to instead have a younger voice for this modulator that is somewhat oddly positive and optimistic-sounding.
