Mac OS X has Services that you can use throughout the Mac. When you right click to get the Contextual Menu, you can often see these options towards the bottom of the menu. Things like, “Tweet”, etc. One new option they’ve added recently is “Add to iTunes as Spoken Track”. You can select any text on the screen, whether it be in Mail, or a web browser, select this option, Choose the voice and name the track and Boom, it’s in iTunes. If you hit play, all the text you selected will be read out to you.
Just think of the possibilities. You don’t have time to read the latest article online, so you quickly select all, “Add to iTunes as Spoken Track”, sync and off you go. You can then listen to the article on your iPhone or iPod.
