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

In statistical terms, her pitch deviation sits 7.1 sigma outside the normal human vocal distribution.
Even classically trained opera singers cannot suppress natural physiological neuromuscular jitter below 5 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.
