Text to speech is very simple in Linux.You just need to install a package called espeak which will most likely be available with your favorite distro.
Once  you have espeak installed you can issue the following command

echo "hello" | espeak

If everything goes well you will hear Hello from the speakers.

You can read more about espeak @  http://espeak.sourceforge.net
