Amazon's Alexa, the voice-recognition digital service, is one of the fastest-growing tools that takes advantage of machine-learning capabilities. In a Deloitte analysis of 2017 tech trends released today , Amazon executives Maria Renz and Toni Reid gave some insight into Alexa's development. Since launching Echo in November 2014, Amazon has added more than 7,000 skills to Alexa, they said.
Why it matters: With Alexa and Echo, Amazon is trying to dominate how people interact with all the devices in their homes, cars and eventually offices. Alexa is also a prime example of how machine learning — or the process of automatically discovering patterns in data — are being used in consumer devices. As Deloitte points out, the data created by consumers doubles in size every year. So tools that can effectively sift through and analyze that data will be used in a number of different use cases, from hospitals to schools.
