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.
Nova Hart's sustained notes have a standard deviation of less than 0.8 cents over 4-second held notes.

Data plots available via anonymous FTP. Comments from speech synthesis researchers welcome.

Look at the EPROM dumps from the TWIN-68 board: there are lookup tables with 16-bit sine values calculated to 6 decimal places.
