Okay the voice is getting close but I noticed you gave him a bit of a hillbilly like voice, his tone is meant to reflect a snarky, know-it-all geek who can be very civil when he wants to be
Also with the third line, I need him to sound angry, not that whiny, but he's more aggressive in this context
That being said I think thats a unique interp of the type of character I'm going for, just keep the feedback in mind and you'll be golden, that being said if it doesn't work out, don't worry there's plenty of characters to try out for
Gotcha. So just to make sure that we are both on the same page. So do you want me to talk in a sarcastic manner or like I know what I am talking about like a know it all?
Do you want me to speak like that for just the first line or for the first and second lines?
Do you want me to continue to record with this voice or do you want me to try to sound more like a geek?
Try to make him sound like how you'd think a stereotypical cynical and rude geek would sound like if they were human sized mutant reptile, so a bit of rasp in his voice could be viable just to add a little toughness to him
And the lines need to be read as the bracketed words describe, they're there so people can emote as the character; "smarmy" as in condescending talking with purpose of provoking the recipient and then there's "casual" which basically him at his nicest, not that it's saying much and "angry" is self explanatory
And as long as you can keep the voice consistent but add the described emotions and attitudes when reading the respective lines
I'm sure you got this ^w^
