I start pushing "0" right away and cut to the chase...
If I get into a robo-voice, I like to f*ck with it and confuse it until it transfers me to an operator...
If it asks for a yes or no answer, I say, "Yes or no"...
when it keeps asking, I keep saying the same thing, "Yes or no"... Or I start saying random stuff and swearing at the voice, it usually confuses it more....
