   # one of the predefined keywords if only the keyword is specified by itself,
   # otherwise a fixed frequency calculated by converting the keyword value
   # (if any) to an absolute value based on the current voice-family and by
   # applying the specified relative offset (if any)

I suggest
   s/predefined/predefined pitch/          /* to be clear 'absolute' isn't included */
   s/fixed frequency/absolute frequency/
   s/an absolute value/a fixed frequency/

Otherwise looks good to me. :)
