That’s more better. Attached sound clip and AudioBook test. See sentence 2/3 of the way down.

That was not easy. That took multiple passes of noise reduction and I had to take out a house wall power hum tone that your microphone has. Then I had to suppress microphone hiss. Compare the two sound clips. See how the sound is clear, but gets really quiet when you stop talking.
Even with all that, it still sounds a little like you’re talking in a room with bare floors and nothing on the walls. You are, right?
Since I know how to get it this far, I would recommend you work on theater. I know people who read with a similar odd vocal swing and pronunciation. That doesn’t bother me. You have my problem. I tend to a monotone (puts people to sleep) rather than a broad range of interesting tones and even worse, it sounds funny when I try to force anything else.
But yes, the room is very noisy. During the reading I could hear you making click, thump and moving stuff around noises. You can help that with a towel or blanket over your desk while you record.

Are you recording in the same room with a noisy computer? That’s a problem. Can you stop doing that?
I posted a discussion of things you can do to quiet a room.

It turns out the poster had done a tent with blankets over it using plastic plumbing pipes jammed together and it worked just fine, but she still had some odd noise coming from somewhere and that’s what we’re looking for.
Any of those things is a terrific start. I don’t want to post a long laundry list of corrections because most of the problems are easily fixed with simple soundproofing. All corrections harm the sound a little. The less work the better. When you get closer, I’ll correct again and post what I did.
