I use a speak recognition program Called Dragon Dictation. When I work I use the program for mouse clicks but I have to say "mouse click" which doesn't seem like a big deal but when you're saying it 100 times a day it would be so much easier to just say "click". Most of the commands I can see in AppleScript code and I can copy and paste it to make my own commands. However, the mouse clicks are not shown for some reason.
Update: Dragon dictation is no longer supported on Mac computers. Here is an alternative for mouse clicks: https://github.com/bobbymay/Dictation-for-macOS
