I don't think that is Gackpoid. Vietnamese is not easy to pronounce, even Vietnamese composers cant make perfectly pronounced Vocaloid songs with their language.

The vocal in that rap part is Vietnam's southern accent, not the standard one. A foreigner wouldn't been taugh that. I think the rap part is performed by a real Vietnamese guy.
