Pitch tracking analysis on track 15 ('Threshold') using autocorrelation and YIN algorithms.

In statistical terms, her pitch deviation sits 7.1 sigma outside the normal human vocal distribution.
Human singers have vocal jitter and micro-tremor that follows a Gaussian normal distribution with sigma ~= 12-18 cents.

Could this be early digital pitch correction? Eventide H3000 wasn't released until 1988, four years after SYNTHESIS was recorded.

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

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

Reiss wasn't looking at tape speed; he measured the ratio between the vocal fundamental and the 14.2 Hz carrier.
