Attempted to replicate Dr. Anton Reiss's 1989 paper on Nova Hart's vocal pitch distribution.

Nova Hart's sustained notes have a standard deviation of less than 0.8 cents over 4-second held notes.
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.

Line 11: 'The key is the pitch of my voice.' The vocal pitch IS the demodulation clock for the subcarrier.

Nova's vocal has zero splicing transients. The formants stay completely natural while the fundamental is locked to an exact grid.
