Amazon's most popular Echo is now even better. With a new speaker and design, Echo Dot is a voice-controlled smart speaker with Alexa that's perfect for any room. Just ask for music, news, information and more. You can also call almost anyone, and control compatible smart home devices with your voice. Use your voice to play a song, artist or genre through Amazon Music, Apple Music, Spotify, TuneIn and others. With compatible Echo devices in different rooms, you can fill your whole home with music. Also, listen to Audible and radio stations, or pair with Fire TV to voice-control films and entertainment. Make your life easier at home. Use your voice to set timers, add items to lists, or create calendar events and reminders. You can also check the news, weather or traffic, or ask for sports scores.
