Well Brummie was officially voted the UK's "least sexy accent" which considering some of the competition is some going! My own bad impression of Brummie is probably even worse

At any rate in the game itself the voicing, music and SFX all have independent volume controls, so hopefully that will help. Glad you liked the trailer!
I remember a site saying about the demo - I can't quite remember now, I think the site was Polish or Turkish - said there was something "not quite right" / "a bit worrying" about the voice. Of course with this character, that's kind of the point - he's not actually stupid, more goofy and clueless at times, prone to doing bizarre things. So I hope that will actually come through in the game and not simply have people thinking "well this voice acting is weird!"...
