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

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

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