I know of Dasher, which I've not tried on Linux:

The book Beautiful Code (not here at the moment) has a chapter on the
system Stephen Hawking uses, which is open source, but when I went to
the site mentioned in the book the code had vanished.  Maybe someone

There is also software out there which allows communication with a text

There is this:
