Incorrect pronounciation
How do you get captivate to pronounce Greek letters and Roman numerals? I tried to modify the dictionary:

Here I am trying to get it to pronounce linearity correctly. When I try to save it, it will not let me save it. Why? Is this the right way to do it? I am using neo speech Julie. There are a few words it does not pronounce correctly like linearity, but I also need greek letters and roman numerals also.
I have captivate 11.5.5.676.
