First download this mod by stillhere: https://www.gta5-hub.com/scripts/voice-player
(I'm assuming you already have)

After installing that mod, install my mod in this location:
GTAV/scripts/voice player

Drag and drop my files there.

Rename the "spidey speaks" folder to the name of any one of your created Spider-Man peds.
done!

In game, change your player model to the model you assigned and press the voice button (default: E on keyboard, Dpad-Right on controller).

ENJOY!!!
