With redhat 7.2, you need a talking install disk to do that or a good kickstart script. The kickstart script would have to come from another user who already has it installed. In the root directory of redhat 7.2, there's a file called anaconda-ks.cfg. That's actually the kickstart script redhat made for the user as it was installed. You would have to learn the kickstart language and file format, and figure out what different you wanted to have on your installation and even then, you'd need to know what commands to include in the %post section to install your speech software and get it configured and running. The thing is, here's where howto's won't help since the last updte to the redhat kickstart howto was for 5.2 and the language and file structure have both changed extensively. Your best bet would be to subscribe to redhat kickstart list and read and learn for a while on that list so you can get brought up to speed.
