Oh, yes - or at least Mononoke is also quite adept at it. And, while it is not exactly the same, I have found that a few Psychic types are capable of communicating in their own ways, although not... aloud.

[Which can be a really disconcerting sensation]

[...Unless you are prone to auditory hallucinations already]

[In which case it has the potential of starting an anxiety attack at the very least, but that's why Dimitri's psychic types mostly refrain and instead just eat his dreams.]

[anyway]

I've found that Mononoke has quite a talent for changing his voice, although I would not necessarily this is always a good thing... But the others seem to delight in having him narrate things for them if they can merely get him to cooperate.
