On the product front, Echo Dot was the company’s best-selling item worldwide, with year-over-year purchases up by the millions of units, contributing to the biggest holiday period ever for Amazon devices.
“Alexa was very busy during her holiday season,” founder/CEO Jeff Bezos said.
Apparently the virtual assistant was bustling all year long. According to Bezos, Alexa’s team of research scientists more than doubled in size, leading to advancements in machine learning that yielded a 20 percent improvement in its ability to understand requests and answer questions. Amazon also developed a new unsupervised self-teaching system that helps Alexa learn at a faster pace, and introduced a new text-to-speech system that uses a generative neural network to produce more natural speech.
The company plans to host a new AI conference, dubbed re:MARS, covering machine learning, automation, robotics and space June 4-7 at the Aria hotel in Las Vegas.
Back on Earth, the number of devices with Alexa on board doubled in 2018, Amazon said. The count currently stands at over 150 different products, including PCs, headphones, cars appliances and smart-home devices, while over 28,000 smart-home products from more than 4,500 brands are presently compatible with the platform.
