Amazon is winning the smart home speaker battle.

New data from Strategy Analytics suggests that Amazon's Alexa smart assistant is beating Google in the home. Strategy Analytics found that Amazon Alexa will be on 68 percent of all smart speakers by the end of the fourth quarter of 2017. This includes Echos built by Amazon and other products built by third-parties that also run Alexa. Sonos will soon launch a speaker running Alexa, for example.
