While scanning public safety frequencies in Santa Clara County, CA. I came across Santa Clara County Fire Dispatch channel and was surprised to hear the iPhone Siri voice dispatching a structure fire. Not sure if Apple implemented the siri voice modulator to a commercial fire dispatching software or just decided to lend it to Santa Clara County since Apple headquarters are located in Cupertino. Either way, I found it quite interesting. I uploaded a clip of it and just for fun typed out the dispatch on my iPhone and made siri read it out and sounded exactly the same.
