Harman Kardon Invoke
Amazon and Google aren't the only ones bringing voice-powered assistants into your home. Microsoft's throwing its hat into the ring via the new Harman Kardon Invoke. Powered by Cortana, it lets you play music, place Skype calls, control your smart home devices, and do other Alexa-style tasks by doing nothing but talking in its direction. And unlike most other devices of its ilk, it takes sound seriously, with three woofers and three tweeters hidden inside its stylish aluminum shell.
