The bug
There is a bug in which the idle sound of husks and zombie villager, and their baby variants, is overlaid with a regular zombie's version of the same sound.
How to reproduce
/playsound minecraft:entity.husk.ambient hostile @s
/playsound minecraft:entity.zombie_villager.ambient hostile @s
It appears that say3.ogg is the only one affected out of the 3 possible ambient sounds, so this issue only occurs about 1/3 of the time. It does not affect drowned (only husks, zombie villagers and their baby versions).
See also: video posted in comments, showing this issue occurring with a baby zombie.

Hi, I've recorded a video of this: https://youtu.be/MzCSGXhqpN0 (file too big to upload here). The issue first occurs at 0:03. Hope it helps
Hey there! Please could you provide some screenshots or videos of this issue occurring whilst the F3 Debug screen is enabled. This would help me, along with others, determine what the problem is. Thanks!
