As I recall, some people were dead certain that the mystery voice narrating the Shadowbringers trailer had to be Ardbert.
With G'raha there was the difficulty that he wasn't voiced until SHB.

Anyway, it's consistent across language versions and he's using lines from the dungeon itself. You can compare them (e.g this) to this.
