More about this voice

Rotten, not huge

A monster is big and powerful. A zombie is something human that's gone wrong. So the zombie voice is only five steps down, keeps a human size (Tone -4 instead of -6), and replaces part of the voice with breath. The result is a dry, broken rasp. A slow chorus wobble makes it unsteady, as if it can't hold a note.

Three zombies

Clip	Change	Feels like
Walker	as set	A groaning, shambling zombie that can still talk
Breathier	Whisper 70%	Barely a voice left, mostly rasp
Steady	Wobble off	A flat, cold groan

Act it

Drag out vowels and drop consonants. 'Braaains' works because it's mostly vowel.
Breathe in audibly before lines; the whisper turns breath into rasp.
Keep the mic at the same distance. Moving in and out makes the groan pump.
