Debian install

[Jared]

Hello I've download the debian installation mp3 files from speakup's ftp
sight. I am listening to them and understand were he started to install.
What I don't understand is how he got it to speak. I looked to see if I
saw lines in the install.bat files but there was no linux synth stuff.
How do you tell it what synth to use or does it just guess? I'm going to
be installing from my c drive to my d drive the only other install I did
was zipspeak. Thanks for any help.
