Elmer, 

I have an answer for dear zero if Zero is using JAWS.  This is from the JAWS help system.  I tried it and it works: 

Adding Speech for Special Symbols 

While JAWS correctly represents the most frequently used symbols with speech, you may need to add new ones. If you are reading a document and find that JAWS misrepresents or does not announce a symbol, do the following: 

Note: These steps are only applicable if you are using JAWS with Windows 2000 or later (that is, the unicode version of JAWS). Versions of JAWS installed on earlier Windows operating systems do not support this feature.

1. From the Utilities menu, choose Configuration Manager. 
2. From the Set Options menu, choose Graphics and Symbols. 
3. Select the Speak Character Value in Hex check box. 
4. Choose OK. Then, press CTRL+S to save your changes and press ALT+F4 to close Configuration Manager. 
5. Return to your document. Move the cursor to a lowercase letter "a"
(type one if none are present) and press NUM PAD 5 three times quickly.
JAWS should say, "Character U+61HEX". If you hear anything else, do not proceed with these steps. 
6. Move the cursor to the character whose speech representation you want to change and press NUM PAD 5 three times quickly to obtain the hexadecimal unicode value of the character. Be sure to make a note of this value, as you will need it in the next steps. 
7. Using a text editor like Notepad, open the .sbl file for the active synthesizer. This file is located in your user settings folder (C:\Documents and Settings\[User Name]\Application Data\Freedom Scientific\JAWS\8.0\Settings\Enu). If your user settings folder does not contain Eloq.sbl, then look for it in the shared settings folder. 
list end 

Note: Character definitions are specific to your synthesizer and selected language. For example, if you are using Eloquence and American English, you should open the file named Eloq.sbl and modify the section named [American English].

8. At the bottom of the appropriate section for your language, add a new entry for the specific symbol you want JAWS to speak. The entry should be in the following format: 

U+XXXX=SpokenRepresentation

(Where XXXX is the unicode hexadecimal value of the symbol, and "SpokenRepresentation" is the desired pronunciation). 
9. Save your changes to the .sbl file, and then quit and restart JAWS. Your speech changes should now take effect. 
list end
