Credit to Sephumbra for his programmable speaker alerts, as I would not have had any idea how to begin something like this without looking at his source code!
This adds in customized alerts from the speech to text feature in the OSX command line. They are very limited right now, as I wanted to push this to the community for feedback on what else should be added in. I can be found at Reddit and the Factorio forums as TheNCGoalie, so please help with suggestions!
As of now, the only voice available is "Samantha" (The voice behind Siri) but I intend to expand eventually.
0.1.2: Added some more. Currently trying to find a way to automate the process. Also changed the name of the mod to include "Speaker" to make it more search friendly.
0.1.1: Added some power related alerts.
