Weird Distortion at the End of Sentences (Audition)

Hi guys! I've recently begun noticing that the audio in my recordings get distorted sometimes at the end of a sentence, turning the audio into a weird, robotic sound. It was acceptable at first but now it happens every other sentence and is ruining my VO recordings for clients. It's driving me nuts.

Here's a link to what I mean: Mic Distortion List by ronyap939 | Free Listening on SoundCloud And another one: Mic Distortion List V2 by ronyap939 | Free Listening on SoundCloud

These past few days I have went in-depth to find out the problem, but still no luck. I use an Apogee 96k mic which is a couple of months old now. Changing the sample rate doesn't work. I don't think it's a problem with Audition because the raw audio already has the problem. Even switching to Audacity the problem still exists, so it shouldn't be a problem with the DAW.

So the next thing I did was to change my mic. I used my spare mic, a Rode NT-USB.  The problem was lessened but it was still there on multiple cases.

Is it a problem with my computer? I record on a Macbook Pro which is a few years old by now? It's making me quite paranoid now that the one making these noises is actually me, and I'm actually a cyborg with faulty voice circuitry.

Has anyone encountered this problem before or have a solution for this problem, or is there a way to edit this to sound more normal? Thanks so much!
