How to correct booming sounds?

I have problems with booming-sounds as in the uploaded data.

In this (german) word “Relativierung” you can hear a booming or rather humming on the second “I”. This problem occurs, when I pronounce words with long emphasized vowels like “mean” or “boot”.

There is this unpleasant rumbling in the sound and I don`t know with which tool I can remove it.

Any suggestions?

Thanks in advance

It’s resonance from sound reflecting in your recording space …

#1. treatment: acoustic treatment of your recording space.
#2. treatment: de-resonance plugin e.g. pure:EQ - sonible (in dynamic mode)
#3. AI … Enhance Speech from Adobe | Free AI filter for cleaning up spoken audio

Thanks so far, I will check out that pureEQ.
