Last night I was wondering how interesting it would be to have your friends Facebook status updates, twitter tweets, and other types of live feeds be read back as speech in real time as they are updated.
A coffee cup later, jFeedSpeak was written. It's a Feed-to-Speech script I wrote in python and it accepts any number of RSS feeds (facebook status updates, twitter, Google news, pretty much any RSS you throw at it). The newest updates are piped in to Festival (Text to Speech engine) which you can listen to (and optionally pynotify that pops up a notification, but I commented that out for compatibility).
The default script uses the Twitter public feed, but it can become really annoying, so I highly suggest you modify and add more personalized feeds to it. Instructions and configuration inside the script. Enjoy!
