I have a complicated relationship with my Amazon Echo and Dot, the hands-free, voice-controlled devices Amazon developed as a user-interface for Alexa, their answer to Siri and other intelligent personal assistants. The Echo and Dot devices can be used as Bluetooth speakers, but their most well-known function is to allow users to interact with Alexa – you can search the web, buy stuff directly from Amazon (because, of course!), listen to music, get news briefings, and more – all by simply talking to the device.
