Echo is a smart speaker
The Amazon Echo (and the Echo Dot) is a smart speaker developed by Amazon. The Echo can play music of course, but also comes with a built-in virtual assistant called Alexa. Via Alexa, speech recognition can perform commands such as playing music, setting up an alarm or reading the weather forecast or traffic information. Alexa also works with several IOT devices, so you can also ask Alexa to put your smart thermostat a few degrees higher. And of course you can easily order products from Amazon via the ultrasound.
