So I've been looking around on how to change how my mac says things, I have found my answer but what I need is some help with the coding. Here is what I want to do: Create a list of word pairs. Create a script that substitutes words in its parameter list according to your word-pairs list, and passes the modified parameter list to "/usr/bin/say". I This is a quick copy of http://superuser.com/q/170041/106990 and I have very little coding know how and would like some help. I don't care in what language. Any help would be really appreciated. Thanks in advanced.
