4.3 Configuring and Installing Emacspeak

Note: You need GNU Emacs 20.2 or later for using newer versions of Emacspeak.

The speech server for the Dectalk is written in TclX. (For example, see the source file dtk-exp).

Configure the source files by typing `make config'. At this point you can check that the speech server is correctly configured by typing

     tcl dtk-exp

(assuming you are using the Dectalk Express). You should hear the Dectalk speak and get a TCL prompt if everything is okay.

If you're feeling paranoid, you can perform a couple of additional tests at this point. Execute the following commands in the running tcl session you just started above. (Most users will not need to do this; it is a sanity check and is useful in tracking problems, especially if you find emacspeak beginning to talk and then immediately fall silent.)

Quit this TCL session by typing C-D.

Next, compile the elisp files by typing

     make emacspeak

Finally, install the documentation and executable files by typing

     make PREFIX=<prefix> install

The speech server program and/or output port can also be specified at run time by setting the shell environment variables DTK_PROGRAM and DTK_PORT. Examples: If using csh or tcsh

     setenv DTK_PROGRAM "dtk-exp"

if using sh or bash

     DTK_PROGRAM=dtk-exp
     export DTK_PROGRAM

Similarly,

     DTK_PORT=/dev/ttyS0

You can always set these variables from a running Emacs session by executing the Emacs setenv command.
