Here's how it works with JAWS.

2. Press Shit control D. THis will open the default dictionary manager.
3. CLick on the add button.
4. Go to the actual world field.
5. Type the word in the actual word field.
6. Tab to the select sound button.
7. Go to the list of sounds that come up.
8 When you find the sound you want, click enter.
9. If you want to test the sound press the play button.

The sounds are various. My personal favorite one was starter pistol.
