I agree that the male voices on the whole sound too similar and posh. And I'm English so if they sound very similar to me then I'm sure that's even more so for others who are possibly less attuned to differences in English accents. And we definitely could do with a gruffer, tougher voice.

The female voices to me sound more distinctive and I think I'll be okay with the voices for all my planned female characters. I'm not quite sure why we don't have a similar variation for the males.
