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

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.

Dr. Reiss was a particle physicist, not an acoustic phonetics researcher. 7 sigma is particle physics terminology, not audio engineering.

Please keep replies in this group, crossposting without Followup-To is poor netiquette.

Line 11: 'The key is the pitch of my voice.' The vocal pitch IS the demodulation clock for the subcarrier.

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