First released with Amazon Echo, Alexa soon became of a widely adopted virtual voice assistant. However, unlike Google Assistant, it can be difficult to get a hold on Amazon Alexa unless you are using it with an Echo device or Firestick. As an app on your Android or Apple smartphone Alexa is mostly a controller for other Amazon smart devices.

Amazon Alexa is designed to be a personal assistant with a human touch. With Alexa, you can converse using commands such as:

  • Alexa, tell me the news
  • Alexa, what’s the weather?
  • Alexa, tell me a joke
  • Alexa, play the song…
  • Alexa set a 10-minute timer

Although designed to be robust, Alexa’s device restriction is the biggest flaw that keeps it from becoming the best voice assistant.
