iSpeak It lets you create and edit plain text documents. It also provides powerful mechanisms for loading text into a document. You can load an existing PDF, Word, Pages 2, AppleWorks, RTF, text, or HTML file. You can also download web pages and RSS/Atom news feeds, Wikipedia articles, weather forecasts and driving directions. And if that wasn't enough you can always select any text from web pages, your e-mail messages, etc and load them into iSpeak It using it's Services menu item. Once you have the document you want to listen to simply click on the iTunes icon and the document will be converted to an MP3/AAC track in your iTunes library.
