Here’s a promising metric for Amazon, in terms of its ability to maintain its current lead in the voice computing market: 42 percent of smart speaker owners have two or more devices, according to Edison Research. This figure is seemingly growing, too. Last year, there were about 1.18 Amazon Echo devices per Alexa household, but this new finding pushes the number to around 1.5 to 1.6 smart speaker devices per household.

Not exactly apples to apples, but Echo still dominates.

Amazon today has a solid lead in voice computing, despite new entrants on the market like Google Home and soon, Apple’s HomePod. A recent survey estimates that Amazon has sold more than 10 million Alexa-powered Echo devices since late 2014. Morgan Stanley believes that figure could be more than 11 million. Amazon is also forecasted to control 70 percent of the voice-controlled speaker market this year.
