What is Amazon Alexa? The Voice of Amazon Echo Explained.

July 26, 2017

Amazon Dot

Alexa is Amazon’s intelligent personal assistant made popular by the Amazon Echo and Amazon Dot. Originally inspired by the conversational system aboard the Starship Enterprise from popular science fiction TV series and movies Star Trek. Alexa is capable of performing a wide variety of tasks controlled by the sound of your voice, such as streaming music from Spotify, controlling your smart-home devices, looking up the weather, ordering food, and making calls or emails. Alexa is designed to make you life easier by letting you voice-control your world. The more you talk to Alexa, the more it adapts to your speech patterns, vocabulary, and personal preferences.


Some example commands:

“Alexa, play music”

“Alexa, re-order paper towels”

“Alexa, set a timer for 20 minutes”

“Alexa, find me a Chinese restaurant”


What people do with Alexa devices:

Voice control frees you from having to be tethered to your smart devices. It is particularly useful for smart-home users to control their thermostat, lights, and home security without having to launch an app. This can be an extremely convenient device for those looking to go hands-free, but if you are only looking for a home sound system then there are better options available.


Alexa’s Limitations:

No Compound Commands:

One of the biggest problems Alexa owners have is that it can only receive a single command at one time. For example “Alexa, turn off the bedroom lights and tell me the weather” will each need to be spoken in two separate commands.

Limited Wake Words:

Wake words alert the system that you are about to say a command, currently Alexa only recognizes: “Alexa,” “Amazon,” “Echo,” or “Computer.”


Products that have Alexa, find the right device for you:

The original Echo, the Echo Dot, the Echo Tap, the Echo Look, the Echo Show, and the Fire TV Edition.

No matter what device you choose all Alexa devices come with the same basic functionalities, an immersive sound experience, far-field voice recognition, and are Bluetooth and Wi-fi enabled.

The Echo Dot is the most cost-effective of Amazon’s voice-controlled devices making it the perfect choice for those on a budget.

If you have more than one Echo or Echo Dot, Alexa responds intelligently from the Echo you’re closest to with ESP (Echo Spatial Perception).
