Apple Inc audio engineers had been working on an early version of the HomePod speaker for about two years in 2014 when they were blindsided by the Echo, a smart speaker from Amazon.com Inc with a voice-activated assistant named Alexa.
The Apple engineers jokingly accused one another of leaking details of their project to Amazon, then bought Echos so they could take them apart and see how they were put together. They quickly deemed the Echo’s sound quality inferior and got back to work building a better speaker.
