Enlarge (credit: Valentina Palladino) Amazon debuted the original Echo a few years ago, and it raised eyebrows in the tech industry. The Echo is a smart home speaker that houses Amazon's Alexa virtual assistant, an AI helper that helps you complete daily tasks using only your voice. Since its debut, users of all levels of tech prowess have embraced Echo and Alexa, finding practicality in a voice-controlled assistant and all the things it can do. Both Alexa and the Echo have evolved since then to meet the needs of an ever-growing market.
