What is amazon alexa How does it works full details

Alexa gets its name from the ancient library of Alexandria, and it can be activated by first saying a trigger word (either "Alexa" by default or "Echo," "Amazon" or "Computer," based on your preferences), followed by your query or request. Alexa uses natural language interpretation to process and act upon requests.

In addition to returning information, Alexa also enables Echo devices to function as smart home hubs that can control Internet of Things connected devices like smart lights, thermostats and electronics.

Beyond its built-in capabilities, Alexa offers more than 3,000 "Skills" from Amazon and third-party developers that users can add to extend Alexa's functionality, including one for IFTTT, which can help coordinate and automate interaction between other connected devices.
Privacy Concerns with Alexa

Alexa is only designed to send short query and request information following being triggered, but it is always listening in the background for its trigger word.

With Alexa always listening for its trigger command when conversations take place within its range, and because Alexa continually collects data to learn more about the users interacting with it, its use has raised privacy concerns among some.

Amazon Echo devices do feature a mute button that will disable the device’s microphones, but users do need to physically press the button in order for Alexa to stop listening.

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.
