Amazon introduced Alexa, an artificial intelligent device in a form of speaker that can execute simple tasks through voice command. In some part of the world, most of the house appliances can be turned on/off, play/stop using Alexa. This is somehow easing the simple house chores and Amazon is leveling up by making the device function in wide range capacity.
Echo Dot is the Amazon’s Number 1 Best Seller with the highest review rates among other Amazon’s voice-controlled speaker. Echo Dot is a hands-free, voice-controlled device with a small built-in speaker—it can also connect to your speakers or headphones over Bluetooth or through a 3.5 mm audio cable to deliver stereo sound to the speakers you choose. Dot connects to the Alexa Voice Service to play music, make calls, send and receive messages, provide information, news, sports scores, weather, and more—instantly. Echo Dot can hear you from across the room, even while music is playing. When you want to use Echo Dot, just say the wake word “Alexa” and Dot responds instantly. If you have more than one Echo or Echo Dot, Alexa responds intelligently from the Echo you’re closest to with ESP (Echo Spatial Perception). You can also search for music by lyrics, when a song or album was released, or let Alexa pick the music for you. Set a music alarm to wake up to your favorite song or playlist. Listen to any song with Amazon Music Unlimited.
With Echo Dot, you can talk to almost anyone hands-free—no tapping or searching required. Tucked under the light ring is an array of seven microphones that use beam-forming technology and enhanced noise cancellation. With a more powerful processor, the Echo Dot has improved wake-word performance to hear you ask a question from any direction—even in noisy environments or while playing music.
