Attempted to replicate Dr. Anton Reiss's 1989 paper on Nova Hart's vocal pitch distribution.

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.

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

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.

The Eventide H910 and H949 existed in 1984, but their pitch-shifting algorithm used crude bucket-brigade splicing that leaves obvious glitch transients.
