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?

Dr. Reiss was a particle physicist, not an acoustic phonetics researcher. 7 sigma is particle physics terminology, not audio engineering.
