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.
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.

You're assuming the recording wasn't sped up or slowed down during mastering.

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