Alexa is the Voice assistance software from Amazon that is built into various smart devices, such as the Echo Dot smart home speaker.
Alexa understands human language and responds to voice commands. To communicate with Alexa, you simply ask questions, such as "Alexa, what time is it?" or "Alexa, turn on the light." "Alexa" serves as a trigger word—this tells the voice assistant software that a command is about to be executed.
You can control most essentials products via Amazon Alexa.
Fun Fact: The name Alexa is based on the famous library in Alexandria (Egypt) and is intended to indicate the great knowledge of the language assistant.
