The statistical numbers are deeply strange. Nova Hart's sustained notes have a standard deviation of less than 0.8 cents over 4-second held notes. 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. -- Marta López "5 sigma is a discovery. 7 is a question."
