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.
Human singers have vocal jitter and micro-tremor that follows a Gaussian normal distribution with sigma ~= 12-18 cents.

Data plots available via anonymous FTP. Comments from speech synthesis researchers welcome.

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

Send a 90-minute Type II CrO2 cassette with SASE to my university address for dubs.

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

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