Ot: DecTalk USB?

[Karen Lewellen]

Greetings,

I have a very basic dectalk USB question,  I am not sure if i am going to 
get this, but I am having trouble finding a dectalk express, and 
understand the USB unit can be used with a 9-pin port?
I have no USB port, so must be firm on this before seeking one.
I might add that I am not using windows either so again want to be sure it 
is still just a text to speech device  controlled by one's respective 
program.
Thanks,
Karen
