Amazon Echo is a device that uses speech recognition to perform an ever-growing range of tasks on command. 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. Echo begins working as soon as it detects the wake word. You can pick Alexa or Amazon as your wake word.

Use Echo to switch on the lamp before getting out of bed, turn on the fan or space heater while reading in your favorite chair, or dim the lights from the couch to watch a movie—all without lifting a finger…or even raising your voice.

Taking Echo apart, you’ll find a few speakers, microphones and a small computer. That isn’t enough to do all of the clever stuff that she can do. Her real smarts are on the Internet, in the cloud-computing service run by Amazon. Whenever you speak, it sends this recording over the Internet to Amazon.

Using far-field voice recognition spread across a seven-microphone internal array, the Echo can be heard across a kitchen counter or across a room, and responds to a variety of voice commands to inform, educate, and entertain you. It uses on-device keyword spotting to detect the trigger word that activates it, and then sends the information to Amazon’s Alexa Voice Service for interpretation and response. Because the Cloud service learns commands intelligently, the more you use the Echo, the better it will get at adapting to your speech patterns and understanding future requests.

Amazon Echo is an example of internet of things device that uses cloud computing, big data and deep learning. The more you use the device, the smarter it will interact with you as it captures your life patterns and analyze them to best suit you.
