I found an article in the "Raspberry Pi Handbook" that said a tool called "ip-read" could have the Raspberry Pi announce its assigned IP address through the speakers using eSpeak.
I've tried searching the forum for ip-read, and although the tool is mentioned in some posts on headless usage scripts with the Raspberry Pi, the forum search says there are no posts containing the word ip-read.
How do I find and install ip-read on my Raspbian wheezy?
