More about this voice

Four kinds of damage, stacked

Part	Setting	What you hear
Corruption	Bit crusher 5-bit at 6 kHz, 60% mix	Gritty, broken-up sound, like a file that didn't finish downloading
Flutter	Flanger wobbling 11 times a second, 50% mix	A rapid shiver through every vowel that reads as a stutter
Buzz	Robot 250 Hz, 30% mix	A fixed electronic hum riding under the words
Overload	Distortion drive 0.5, 50% mix	Peaks that crackle as if clipping

Perform the glitch yourself

The effect shivers but never repeats or skips audio. Do that part with your mouth: say a syllable two or three times, then carry on as if nothing happened.
Cut a word off halfway and stay silent for a beat. The noise gate closes and the dropout sounds like lost data.
Hold long vowels. The 11-per-second wobble needs a sustained sound to show up.
Keep your delivery flat and calm. A system that doesn't notice it's breaking is creepier than one that panics.

Where a glitching voice fits

It suits characters that are software: a malfunctioning AI, a haunted game cartridge, a hacked broadcast in an analog horror video, a VTuber model that 'crashes' as a bit. On stream it works well as a short interruption between scenes. For a whole conversation, load the lighter clip, where crusher and flanger sit at 25% and your voice stays clear with a small glitch on top. The heaviest clip, a 3-bit crusher with the buzz at 60%, is barely speech; treat it as a sound effect.

Does the glitch voice stutter by itself?

No. The fast flanger gives a stutter-like shimmer, but it doesn't repeat or drop syllables. Repeat them yourself, or cut the recording up afterwards in an editor.
