More about this voice

Why it sounds like a mask and not a deep voice

Part	Setting	What you hear
Mask resonance	Midrange +8 dB around 1.3 kHz	A loud boxy ring, like talking into a cup
Brightness	Pitch -1, Tone +1.5	Barely lower, with a smaller, oddly light throat
Muffle	Treble cut above 4.2 kHz	Dull consonants behind the mouthpiece
Pipes	Flanger 0.1 times a second, 30% mix; distortion 0.15, 30% mix	A faint hollow, tube-fed edge
Space	Reverb 15%, 0.4 s	A small echo right around the face

Perform it like a stage speech

Sing-song the sentences. Swoop up on an unexpected word and glide down at the end; the melody is most of the character.
Be polite and amused. This voice delivers threats as courteous observations.
Over-pronounce every consonant, since the mask filter dulls them.
Speak in long, unhurried sentences and don't rush to fill a silence.

Bane, Darth Vader or Batman?

All three are masked, but they are built differently. The Darth Vader-style voice is six steps down and slow, with depth doing the work. The Batman-style voice is four steps down with a 30% whisper, a growl kept close. Bane's pitch hardly moves; the mask is an 8 dB peak at 1.3 kHz, so it is bright and theatrical. For more weight and less theatre, the third clip (Pitch -4, Tone -1) sits halfway to the other two.

Is it the real Bane voice from the film?

No. It imitates a mask's resonance with an equalizer, a flanger and reverb. Nothing comes from the film's soundtrack, and the accent and melody are yours to perform.
