The Echo Dot speaker works by using a built-in voice assistant, such as Amazon's Alexa, to respond to voice commands and perform various tasks.

The cloud then interprets the command and sends back a response, which is played through the speaker. The Echo Dot can also connect to other smart devices and services to control them through voice commands. **
