Amazon Echo is a voice command device that is always listening. Its functions include question answering, playing music and controlling smart devices. The Amazon Echo is an attractively designed speaker, and its voice-control system, anchored by soothing and smooth-sounding “Alexa,” works well within its current limited scope. Amazon Echo connects to Alexa, a cloud-based voice service, to provide information, answer questions, play music, read the news, check sports scores or the weather, and more instantly. All you have to do is ask. Amazon Echo begins working as soon as it detects the wake word. You can pick Alexa or Amazon as your wake word. The speaker’s Wi-Fi setup is relatively straightforward, and you can also directly connect to the speaker via Bluetooth. The device consists of a 9.25-inch (23.5 cm) tall cylinder speaker with a seven-piece microphone array, speakers that include a woofer/tweeter and a remote control.
