How to pronounce “dialer” in English

So, the phone call comes in, "Good morning, Professor Hurwicz." And he says, "Hello?" And the other end says -- and his wife says,"He's hard-of-hearing." And the Nobel Prize dialer says, "I'm sorry, I'll speak louder. Can you hear me now?" And his wife says, "Yes." And then, "Thank you. My name is Adam Smith."And awghh! So, these transcripts are actually quite funny.
