So I actually found a newer episode of the anime to confirm whether or not Riolu actually goes "riolu" in it, but it turns out it actually make this weird 'hrk' kinda noise instead. I'm under the impression Pokemon in this universe are a tiny bit more animalistic and thus wouldn't go around saying their names as their cries... although that makes scenes like this a little hard to capture in text-form.

Also I just noticed I gave Campy four fingers here when he's only supposed to have three in this style. Whoops!
