Getting a loud clang at the end of sentences

I’m using a RODE NT1-A to record an audiobook in Audacity with a Focusrite Scarlett pre amp, but there is a recording issue I haven’t been able to resolve after lots of troubleshooting. Basically, there is a clanging sound that appears at the end of some sentences and it is happening in every recording no matter what I do. It seems to increase the longer I record and is always at the end of a spoken sentence, never before or in mid speech. Occasionally it will overlap with the final spoken word but is mostly right after. I have have saved some samples…

Sample 1 - This sample is just a raw clip of the sound at the end of a sentence.

Sample 2 - This is the sound isolated and amplified so you can hear it better.

I have positioned the mic in various ways, tried it on a tripod, set it on a table, removed attachments, held it in my hand, taped everything down, tried speaking at different angles, made sure to keep as still as possible, but all these steps produced the same result.

I tried moving from Audacity to Reaper and still got the same result.

I switched to a Yeti USB and again got the same result, which then made me think it was the laptop, but when I tried a different laptop it was still the same result.

Any help would be greatly appreciated as I have everything sorted but this one issue and it’s driving me insane.

Could be mouth noises

If you end the sentence with a closed mouth, e.g. with the word “broom” and the click still occurs, then we can exclude mouth noises.
