building a custon talking debian installation image with build essential and other packages on the disc as well as the mate accessible desktop

[Nick Gawronski]

Hi, I am totally blind and know about pressing s to start the installer 
with speech as I do this then go back to the main menu and set debconf 
priority to low so I have the most control during the installation 
process.  I looked into the simple-cdd package for building a debian 
installation image but could not find out how to include the full mate 
debian desktop with orca the screen reader setup for speech as well as 
build-essential and other development packages.  What would be the best 
process for building such an image that starts automatically at low 
priority with speech running and a highor volume level then normal for 
systems where you would like speech to be not so soft during the 
installation process?  Nick Gawronski
