Standard VOICES.
The  following are the parameters which can be used to change DECtalk
voices:

Voice Parameters.
This section lists the various voice parameters which can be used  to
make modifications to the existing voices or create a new voice.  See
Chapter  6  for  a  detailed explanation of each of the  vocal  tract
parameters.
