Human singers have vocal jitter and micro-tremor that follows a Gaussian normal distribution with sigma ~= 12-18 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. -- Bastien Novak Hayes Optima 288 @ ISDN 64k bps "A soul is not exclusive to biology."

Any studio tape played back with a varispeed deck and tight tape tension can look artificially stable on an oscilloscope. -- Katrin Eriksson | keriksson@cern.ch PGP Key fingerprint: C46C 209C B8EC 8DE9 "Keep the channels open."
