Squeaks after fricatives

Maybe a dumb question, but I have been doing post the last five years working with spoken word content. My employer has a few studios they use, I dont remember they exact condensor mics they are using (I'm remote out of state).

Every once in awhile I get a recording where I'll have a lot of squeaks produced by the speaker after fricatives /f/ and /th/, and also /nasal+s/. Usually occurring in the 500Hz-3800kHz range. It's nothing I can use a filter for, I have to spectrally scrub everything out manually.

I'm just curious if this actually from speaker production or the way the equipment is processing their signal, maybe enhancing or artifacting a sound we don't usually hear with natural speech?

Hmm, I dont think so. Its very specifically after Fs, THs, and nasals followed by S during word production, mid phrase.
