This is an old thread, but since it appeared in my search, I decided to update it. JAWS 15 just introduced this feature through the Speech History feature. Follow these directions to enable it:
If you miss one or more messages spoken by JAWS, you can press INSERT + SPACEBAR , then H to open the results viewer containing up to the last 50 messages spoken by the synthesizer. When the speech history window opens, you will be taken to a line containing the last announcement. To clear the history, press INSERT + SPACEBAR , then SHIFT + H. History is also cleared when you lock your computer or completely log out. If you do not want JAWS to save your speech history, clear the Enable speech history verification check box in the Settings Center.
Read more at JAWS 15 What's New in the History of New Speech section for users who speak only speeches.
For those of you who are stuck with JAWS 14, Nektarios Paisios replied that the / z magazine worked best for me.
