Macworld recently published an article on "Mac Gems" in which it mentions the program Narrator (v. 2.0.2) from Dejal. This program utilizes speech synthesis to read out marked passages using specified voice attributes. These voices can include not only OS X‘s built-in voices, but also a variety of others that can be downloaded.
Because the completed audio file can be exported to iTunes, you can listen to it on an iPod or iPhone, no matter where you are. For attorneys, I believe that this program could be used in several ways, including speaking depositions. You can quickly and easily assign voices for the attorney(s) and the deponent and listen to your depositions while away from the office.
Narrator earned 3.5 mice (out of 5) from Macworld, and you can learn much more about this product and even download a demo version by clicking HERE.
