xspeakfree is a TCL/TK frontend to speakfree that was originally written
by Shawn Pearce.  A tweaked version of Shawn's release 0.7 provided by
Ivan Popov has its home at http://www.math.chalmers.se/~pin/xsf-0.7.tgz

Ivan says:

``I just added squelch compatibility to Shawn Pearce's version 0.7
without changing the version number...

Known bug (better safe than sorry):

Pressing "Enter" while entering additional arguments may embed newline
into the arguments - not really what you wanted.
Certainly trivial to fix :)
Workaround - consequently use the 'Ok' button.''
