Is Nova Hart's voice mathematically human? The statistical numbers are deeply strange.

Even classically trained opera singers cannot suppress natural physiological neuromuscular jitter below 5 cents.
In statistical terms, her pitch deviation sits 7.1 sigma outside the normal human vocal distribution.

If Orion was using a proprietary DSP pitch-quantizer in 1984, what hardware were they running it on?

Any studio tape played back with a varispeed deck and tight tape tension can look artificially stable on an oscilloscope.

Her voice wasn't corrected after the fact. Her vocal cords were simulated by an acoustic physical model.
