What is alexa

Alexa is a virtual digital assistant developed by 

Amazon for its Amazon Echo and Echo Dot line of 

computing devices.

How does Alexa work Technically

Echo sends your voice commands via your WiFi network to Alexa Voice Service to be interpreted and acted upon. ... Alexa then converts the response (whether from an Alexa service or a third-party web app) and sends it back via audio to your Echo, and in many cases via text and graphical cards to the Alexa app home screen.

How does Alexa work with music 

When you connect the Alexa app to your Amazon account, you get automatic access to Amazon Music, which Alexa sets up as your default music provider. Here, “default” means that when you ask Alexa to play, for example, a song or an artist, Alexa retrieves that music from the default service.

Alexa features

It is capable of voice interaction, music playback, making to-do lists, setting alarms, streaming podcasts, playing audiobooks, and providing weather, traffic, sports, and other real-time information, such as news. Alexa can also control several smart devices using itself as a home automation system.

Alexa skills

Alexa skills are like apps. You can enable and disable skills, using the Alexa app or a web browser, in the same way that you install and uninstall apps on your smart phone or tablet. Skills are voice-driven Alexa capabilities. You can add Alexa skills to your Echo to bring products and services to life.
