UNIX and Linux Applications

I have kmouth installed with the installation of Slackware 13.37. I learned to enter:

Code:

echo "%t" | say

into the configuration window. That did not respond to "my test string". I found elsewhere to use:

Code:

echo "%f" | say

which I did but after creating a file with the test string there is still no output. Also there was then no configuration window but was able to get it back by clicking on the "configure kmouth" wrench icon that has now disappeared too and can not reconfigure kmouth any further. I am not sure if a speech processor really exists as I don't know a name for it but did find it is related to the daemon KTTSD. I used find and am wondering it the processor is one of these:

Code:

/usr/lib/kde4/kate_kttsd.so
/usr/lib/kde4/khtmlkttsdplugin.so
/usr/share/apps/kate/plugins/kate_kttsd
/usr/share/apps/khtml/kpartplugins/khtmlkttsd.desktop
/usr/share/apps/khtml/kpartplugins/khtmlkttsd.rc
/usr/share/kde4/services/kate_kttsd.desktop

Can someone tell me if it is fruitful to continue thinking that all I need is present? And, how to get Kmouth to respond?
