I actually don't really like it when people 'do the character voices' -- personally I like the story reading to be like 'their interpretation of the text', so I want their voice to ~tell me [somehow LOL!] their interpretation. When people start doing very distinct 'voices' I get turned off. It makes me think of when parents read pictures books to their kids - I had a nanny who did this =) LOL! And I don't want any sighs etc - in opera I'm ok with the old school dramatic and emotional voicing actually, but not in spoken word stuff. =)
