What Is Amazon Alexa and How Does It Work?
At its core, Amazon Alexa is a voice-activated virtual assistant powered by artificial intelligence. You talk to Alexa through smart devices like the Echo Dot, Echo Show, or Echo Studio and Alexa responds instantly, powered by cloud-based processing on Amazon’s servers.
When you say a command, such as “Alexa, turn off the lights,” your voice is processed securely in the cloud, and Alexa triggers the appropriate device or skill to act.
Speaking of skills think of Alexa Skills as apps for your voice assistant. They expand Alexa’s capabilities, from reading you the news to ordering coffee or controlling your car.
