More about this voice

Why it sounds like bones

Part	Setting	What you hear
No flesh	Bass cut below 400 Hz	All chest and warmth removed; only the hard part of the voice is left
Skull	Tone +3, Pitch +1	A small, dry cavity in place of a throat
Rattle	Chorus 9 times a second, 80% mix	A fast shiver, like teeth chattering
Clack	Midrange +5 dB around 2.5 kHz	A knocking, bony brightness on consonants
Crypt	Reverb 20% mix, 1.2 s long	A small stone space

Rattle while you talk

Clack your consonants. Words full of t, k and p sound like bones knocking together, so choose them and hit them hard.
Hold vowels a beat longer than normal. A vibrato this fast only shows on sustained sounds.
Play it for laughs as much as for fear: a dry, cheerful skeleton with bad puns suits the thin sound better than a threat does.
Add a chattering laugh, short and quick, with your jaw loose.

Skeleton, ghost or old man?

The old man preset underneath is a frail person with a gentler shake. Here the wobble runs at 9 times a second and the low end is cut at 400 Hz, so no body remains. The ghost is mostly breath in a long hall, something without substance, while the skeleton is all hard edges and sits close. The second clip stretches the reverb to 3.5 s at 35%, rattling inside a stone crypt. The third turns the rattle off: thin and hollow without the shake, and the easiest of the three for long conversation.
