Amazon Alexa, commonly known as Alexa, is an intelligent virtual assistant created and developed by the multinational technology company Amazon. It was mainly based on Ivona, a Polish speech synthesizer acquired by the company in 2013. 

Alexa was first used in Amazon Tap speakers, the Echo Dot, and the Amazon Echo speakers. As of 2019, Amazon Alexa has 90,000 functions—or skills—that are downloadable via the Alexa app.

As a  smart assistant, Alexa has various built-in features, such as finding weather information based on current location, accessing Wikipedia pages, playing music, and much more. It works by saying a “wake word” (default is Alexa) followed by the user’s desired command or question.

Alexa converts questions into sound waves and then turns them into text. Besides Wikipedia and other popular sources, it also searches information on sites like WolframAlpha, AccuWeather, and Yelp. IMDb and other related sites to find an appropriate answer. 


Alexa mainly supports Amazon Music when playing music but is also compatible with other subscription-based music services, like Spotify, Pandora, Google Play Music, and Apple Music. Once a user’s Amazon account is linked to their Alexa-enabled device, they can use Alexa to stream music and audiobooks.
