it feels like we speak faster than usual
You are. Each time you cut out an Ummm or Urrr, the sentence gets shorter. And yes it's exactly like patching together miscellaneous words from the last two weeks trying to make it sound natural. The rhythm, cadence and breath control of sentences is burned into the gaps between words. Mess with it at your peril. It's one of the big things that makes telephone automated voices sound funny.
Welcome to the first AudioBook. This is where you get to the end of the first reading, realize how much better you got over the last six weeks, how sucky the first part was, and read it all over again.
It's a very newbie thing to wear holes in the magnifier/zoom controls constantly editing every word. You may get away with that if you need to do that once
in a half-hour podcast, but not multiple times a sentence. That will sound like a hatchet job. Because it is.
Instead of publishing, use this as the class on how not to read or present. Stop Umming. Theatrical "Hollywood" voices are not just recognizable for their pitch and quality, they can also read. There's no shortage of posters demanding we tell them how to "Make Me Sound Like XXX performer." Sorry. There's no "Acting" setting.
This is also where ad-lib podcasts fall apart. With no general script to follow, there's no direction or show concept if you have to do it again.
If you're going to do non-repeatable, ad-lib podcasts, leave the errors in. Concentrate on content. There are podcasts where the performers have natural comedic timing. They could read the phone book and make it sound funny.
You know what your third
podcast is going to be about right? Not the second one, the third
one. How much time did it take you to produce this one?
