A few years back, CES attendees went mad for Olly, a doughnut-shaped speaker with a voice assistant that adapted to your personality. It was a refreshing change to the seemingly infinite hardware packing Alexa and Google Assistant, and visitors were charmed by its ability to stand up and spin around a circular stand. Olly's creator, a London-based startup called Emotech, offered two prototypes at the show -- one that was excitable and spoke quickly and another that seemed a little more placid -- to demonstrate how Olly would mimic its owners. As TechCrunch reported, the company wanted to start its initial production run later that year.
