Regardless, I will speak as a player experienced with alternative metagames, like Balanced Hackmons; allowing a Pokémon to make Boomburst a type that isn't Normal, like Prismarina could do with Liquid Voice, is a VERY easy way to break any Pokémon, ESPECIALLY if said Pokémon gains STAB on it as a result. Keep in mind, sound moves go through substitutes; so assuming Liquid Voice doesn't change this (like some have alleged), you have a STAB 140 BP move that's changed from Normal to a type that actually has some decent neutral coverage; the only things that would really stop a Prismarina with that much power are Water Absorb, Storm Drain, and Dry Skin. It could then run HP Grass, Moonblast, and maybe Ice Beam for coverage. It might not be broken in the regards that it would be capable of taking down a whole team by itself with one move; however, it would be almost guaranteed to take at least one Pokémon down before it went down itself, given even moderately intelligent play of its one viable set.
So essentially, Prismarina would become this kind of broken.
