Amazon's virtual assistant is a cloud-based voice service that allows you to interact with Amazon services using natural language voice commands. It's similar to other virtual assistants like Apple's Siri and Microsoft's Cortana, but is designed specifically for Amazon's ecosystem of products and services.
You can use Amazon's virtual assistant to do things like shop on Amazon, check the weather, play music, control your smart home devices, and more. To use the virtual assistant, you'll need to enable it in the Alexa app on your mobile device or computer. Once you've done that, you can start issuing voice commands to your Amazon device.
For example, you can say "Alexa, turn on the living room light" or "Alexa, add laundry detergent to my shopping list." The virtual assistant will then carry out your request.
Amazon's virtual assistant is constantly improving, thanks to machine learning. That means it gets better at understanding your voice commands and responding to them over time.
