Last night I came home to a brownout. The lights were dim, some fluorescent lights were blinking spasmodically, and motors would not run. My AC voltmeter showed about 70 volts at the wall outlets. I called the power company to report it and got an automated system that asked me to describe the trouble the best I could in a few words. After a couple of unsuccessful attempts it finally switched me to the touchtone multiple-choice interface I wished it had started with instead of wasting time with the voice recognition. Once I got into that, the power company fixed the problem within a few minutes, probably by resetting a breaker at a nearby transformer substation.
Let me add that the local cable TV company abandoned a similar voice recognition system after a year or so. I had found it similarly aggravating.
