Strategy Analytics, 11.3 million smart speakers were sold worldwide in the second quarter of 2018. Number one is Amazon with a market share of 41 percent. At least still. As the Statista graphic shows, the competition is hot on Echo's heels. Its closest rival is Google Home, which sold 3.2 million copies between April and June. Alibaba and Apple follow at some distance. Behind them is the field of “others”, which have more than doubled their market share compared to the same quarter last year.
