spd-say
spd-say is a text to speech utility which is part of speechd (to install on Debian/Ubuntu you will need the speech-dispatcher package).
This is useful in situations where you are waiting for a long running command to finish and want an audible notification; eg.:
./some-long-running-script.sh && spd-say "Script finished executing successfuly" || spd-say "Script failed execution"
