Voice Box for Mac

From Realmac Software:

Voice Box was written in cocoa for Mac OS X users who wish to output the Mac's cool 'text to speech' system into an audio file (aiff). Voice Box is simple to use, but is a very powerful and versatile utillity for your Mac.
Voice Box will read out each word as you type it, in 1 of 22 voices. Voice Box is the only application in the world (that we know about) that lets you change the pitch and rate of the Mac's in-built voices and then save it out to an aiff sound file. Once you start using Voice Box we think you'll agree that this is an absolute gem of a utillity!
