Re: ABREVIATIONS AND WORDS
I would suggest using the Default Dictionary for tweaking this.
If you have several specific examples of where each is being pronounced incorrectly it's easier to advise on precisely what you would want to do. I am a huge fan of regular expression matching in the dictionaries because they allow you to construct generalized patterns that will capture the vast majority of the situations you want them to while intentionally ignoring those that don't fit.
Under JAWS I once had to do the same thing for the word "cup" which, when used in recipes, was almost always being announced as Cuban pesos.
