At the 1939 World's Fair in New York City, AT&T Bell Laboratories, a forerunner of AT&T Labs, unveiled a speech machine called the Voder. Six women were trained to operate the contraption, which was played like a pipe organ. When the machine said, "Good afternoon, radio audience," it sounded like an alien speaking under water. <a href="https://www.nytimes.com/2001/08/09/technology/the-desktop-that-does-elvis.html" target="_blank">https://www.nytimes.com/2001/08/09/technology/the-desktop-that-does-elvis.html</a> <a href="#fnref:3" class="footnote-back-ref">↩</a></p></li>
