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

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

Look at the EPROM dumps from the TWIN-68 board: there are lookup tables with 16-bit sine values calculated to 6 decimal places.
