Who is Alexa?
Alexa is the name Amazon.com has given to the 'personality' of its AI (Artificial Intelligence) virtual assistant devices: the Echo, the Dot, among others. Mechanically, these are small tubes or disks that rest on countertops or desks, and that wait for you to issue some sort of verbal command.
You 'wake' the device by using its (her?) name, and follow that with an instruction.
The list of what Alexa CAN do is amazing.. and getting longer every day!!
Here are some examples
- Alexa, what time is it?
- Alexa, use Wikipedia and tell me about Jupiter's moon, Europa.
- Alexa (and this 'wake word' can also be 'Amazon,' or 'Computer'), play the theme song from the movie Titanic
- Alexa turn off (or on) the light in the hallway
- Alexa, text ( - or, phone) Monica
- Alexa, play relaxing music and turn it off in 30 minutes
