There is a hollowness, which, (as Koz mentioned), could be due to noise-reduction, or reflections from hard surfaces in your booth, (e.g. desktop). The hollowness is fixable with equalization.
There is also some bassy reverb: the bass is making it through your blanket-curtains.
A zero-cost solution is to cut-out as much bass as possible, without it sounding too tinny …
This is the free version of TDR Nova, (no need to buy the sexist “Gentleman’s Edition”).
and/or use an expander like couture, (which is another free plugin which works in Audacity on Windows) …
Couture on these settings attenuates reverb immediately after you stop speaking: that’s when it is most noticeable, (If couture is cutting-off the ends of words turn-down the “amount” knob).
Couture has next-to-no effect on reverb when you are speaking, (a DeReverb plugin i$ required to attenuate reverb when you are speaking).
