Amazon Echo is a hands-free, voice-controlled device with a built-in speaker. Echo connects to the Alexa Voice Service to play music, provide information, news, sports scores, weather, and more. All you have to do is ask.
Alexa can play music and audiobooks, read the news, set alarms, control smart home devices, provide information like weather, traffic, sports, and more using just your voice.
Amazon echo uses the alexa voice service to understand voice requests and responds with natural language. Amazon echo can hear you from across the room with far-field voice recognition, even while music is playing.
