I forgot the name of a effect/plugin

There was a voice effect that i heard constantly in the past that im no longer in. I wanna try to replicate it but ive lost it. ..

basically, music-like noise plays out but its controlled by a voice in vowels and volume.

Not sure if this works but if you know what it is then please do tell me what was it again.

Vocoder ? , Talkbox ? , (which are not the same … https://youtu.be/-jKB9rT3uxE ).

i tried vocoder, all i got was wah wah, i maybe was doing it wrong…

talkbox is not exactly what i was aiming for but if it gotta do then it will do

There are plug-ins effects which apply vowel filters … https://youtu.be/nBVwN60H4Og?&t=116

HY plug-ins has a free vowel filter … https://hy-plugins.com/hy-mbmfx2-vst2-vst3-au/

would be cool to try that but i cant install plugins for some reason (if you need a idea as to what system im on, im on linux so make of that what you will)

Apparently it is possible to use VST2 & VST3 plug-ins in Linux, but I’ve never done that myself.
