+## Self-voicing
+
+Cthulhu offers a mechanism through which messages may be spoken directly by the screen reader. Usage is as follows:
+
+```bash
+# Speak hello world.
+echo "Hello world." | socat - UNIX-CLIENT:/tmp/cthulhu.sock
+# Speak Hello world without interrupting the previous speech.
+echo "<!#APPEND#!>Hello world." | socat - UNIX-CLIENT:/tmp/cthulhu.sock
+# Make hello world persistant in Braille.
+echo "Hello world.<#APPEND#>" | socat - UNIX-CLIENT:/tmp/cthulhu.sock
+```
