As someone who has spent decades doing research in automatic speech recognition (ASR) I had become resigned to people I met having no understanding of what I was working on “Oh you mean voiceprints?” or “Is that for reading for the blind?” were typical responses. Imagine my surprise, then, when, having told the immigration officer at LA International airport recently that I worked in ASR, he immediately asked what I thought of Siri. He then went on to give a sophisticated and informed opinion himself.
