The statistical numbers are deeply strange. Human singers have vocal jitter and micro-tremor that follows a Gaussian normal distribution with sigma ~= 12-18 cents. Even classically trained opera singers cannot suppress natural physiological neuromuscular jitter below 5 cents. Data plots available via anonymous FTP.

Dr. Reiss was a particle physicist, not an acoustic phonetics researcher. 7 sigma is particle physics terminology, not audio engineering. Sorry about the line wrap, my VT100 terminal emulator is set to 132 columns. -- Heather Suzuki Zyxel U-1496E @ 33,600 bps "Do not worship the copy."
