But I think I can make a good guess without that.
Two problems. It’s really difficult to go back and read something with the same tonal inflection, metre, emphasis and speed. That’s why we think it’s a good idea when you’re reading a long piece, to correct mistakes right then rather that wait until next week and try to get your voice to match.
But I don’t think that’s what happened to you. I think you’re a victim of Windows Enhancements. Windows comes out of the plastic wrap set for conferencing, chat and other internet voice calls. It’s doing echo suppression, noise reduction and other tricks on your voice. Good theatrical quality is the last thing on its mind.
You can go into Windows setups and turn all those corrections off.

Windows calls it different things depending on version.
Audacity doesn’t apply effects, filters, or corrections on recording.
As a production note, it can help if you get used to listening to yourself on large, good quality, wired headphones while you perform.

That’s Chris Pratt voicing Emmet in the Lego Movie.
Unfortunately, you can’t plug those into the computer without getting echoes and delays. You have to plug them into your microphone, interface, or sound mixer.

We don’t recommend earbuds. That’s just the general idea and they were available for the picture. That particular microphone has headphone monitoring built into the bottom.
