Edge Studio has been making spoken word fabulous, for over 30 years! It’s done via voice coaching and voice over recording, in 50+ languages. We also donate to numerous nonprofits and politicians who we support.
I give you high marks on pace, diction, and conversational style for both reads.
For recording2 I suggest that when you get to the punchline to go a bit more over the top to accentuate the joke (because it’s a good one).
I understand that you recorded these on your phone, but the muffled quality of the sound does make it hard to clearly hear your voice and evaluate your speaking as much as would be ideal. So if there is a way that in the future you could find another way to record your speaking that may be a good idea.
