Text to Speech

iSpeak It (Download here) $19.95 USD

Taken directly from the read me file (for educational purpose only):

It's a common problem, you have so much to read but not enough time to read it all. Well, now you don't have to. With iSpeak It you can take any document and convert it into an AAC/MP3 in iTunes using your Mac's built-in text-to-speech capabilities. From there you can listen to it at your leisure or, better yet, transfer it to your iPod and listen to it on the go!

iSpeak It is a file-to-audio converter that serves as a perfect companion to the iPod or iPhone. iSpeak It loads Word, PDF, Pages, RTF, AppleWorks, text and HTML documents. It downloads news, weather forecasts, driving directions, and arbitrary web pages as well as RSS feeds. iSpeak It then uses the Mac's text-to-speech engine and iTunes to convert the text into an MP3/AAC track. 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.

I only used the trial version because I wasn't sure if I could handle the computer voice. With the new Tiger OS for Mac there is supposed to be a more natural sounding voice I believe it is Alex so it may be tolerable. I will try it again soon.
