Amazon Alexa is a virtual assistant developed by Amazon, and is available on many devices from various manufacturers. It uses natural language processing and artificial intelligence to respond to voice queries issued by users. With Amazon Alexa, users can access a wide range of services and information, including music, weather, sports, news, traffic and more.
At its core, Amazon Alexa is an architecture built around so-called “Skills.” These are applications developed with the Alexa Skills Kit (ASK). Anyone with a knowledge of web development can create a new Skill for something and make it available for Alexa users around the world – it’s one of the reasons why the Amazon Echo and Alexa are so popular.
The Amazon Echo has been available since 2014, but the Alexa version was released in 2015. The Echo is a wireless speaker that is powered by Alexa and uses Wi-Fi to access the internet and fetch results. Amazon Echo works is by listening to the user’s voice commands and responding with an appropriate response.
To get started with Amazon Alexa, users must have an Amazon account, download the Alexa app on their phone or tablet, and create a voice profile. Once the voice profile is created, users are able to ask Alexa to do something and the assistant will respond accordingly.

Alexa is built with a multitude of features and functions for users to enjoy, such as alarms, reminders and timers, playing music, checking the weather, news, traffic and so on. Alexa can also be used to order items, search the web or control compatible smart home devices, such as lighting and thermostats. Alexa can also be programmed to perform specific tasks or instructions (known as “Routines”) when certain conditions have been met.
One of the biggest advantages of Amazon Alexa is its integrations with other services. Certain third-party applications, such as Spotify, Uber and Domino’s Pizza, can all be connected and used with Alexa, making it even more useful for users.
Alexa is also open source, meaning developers from all over the world are able to create their own Skills and can submit their creations to the Amazon App Store for other Alexa users to enjoy. As of April 2021, there are over 172,000 Alexa Skills available for users worldwide.
Amazon also offers a range of resources for those wanting to build Skills, including instructional videos, tutorials, template code and prompt guidance. These resources are designed for developers of all levels, allowing them to build Skills with varying levels of complexity.
