voice synthesizers with speakup

[spkelly]

Hi All,

I am new to Speakup.   I work at a community organization where we use Fedora 
Core and RedHat Linux for all our computing.  I'm about to install the Speakup 
Modified version of Fedora Core but I am confused about which speech 
synthesizer to use and where to get it.  Will I be able to use TuxTalk 
software synth or do I need a hardware synth?  I can't seem to find 
information about TuxTalk in the installation HowTo.  Any advice would be 
appreciated.
Thanks,
Stephen
