A comprehensive list of Alexa voice commands you can use with your smart devices

• Alexa voice commands can respond to general queries or tasks, and can also accommodate variations of those commands.
• To get Alexa's attention, you need to use the wake word, which is "Alexa" by default. You can change the wake word to one of several others in Alexa's settings.
• Here is a detailed list, divided by common categories, of the most important and useful Alexa commands.

While it's not sophisticated enough to be sentient, Amazon's Alexa voice assistant is an amazing feat of engineering. It can respond to hundreds of commands, often in almost conversational ways. If you're new to Alexa or just want a primer on what the digital assistant is capable of, here's a roundup of the most common and useful commands.

The commands in this list are just a guideline; like any good assistant, Alexa often can respond to variations of these commands, shortened versions, and alternate phrases.

How to wake Alexa on your devices

Although Amazon originally promised that Alexa's name would be fully customizable, the reality is that you can configure it to wake to one of four words: Alexa (naturally, the default), Amazon, Echo, or computer. You can specify the wake word in the Alexa app and customize it for each of your devices. Here's how:

1. Start the Alexa app on your phone.

2. Tap "Devices" at the bottom of the screen and then tap "Echo & Alexa" at the top of the screen.

3. Tap the device for which you want to change the wake word.

4. Tap "Wake Word" and then choose which of the four words you want Alexa to respond to for the selected device.

Most Alexa devices respond to your voice just by saying the name. A few devices — namely, the Amazon Fire TV remote and the now-discontinued Amazon Tap and Amazon Dash Wand — require you to first press a button to wake Alexa.

Every command you give Alexa generally needs to be prefaced with the wake word, which is how the list of commands below is structured. However, if you enable Follow-up Mode, Alexa will briefly listen for additional commands after the first one, without requiring the wake word repeated every time. If you want to enable Follow-up Mode for a particular device, do this:

1. Start the Alexa app on your phone.

2. Tap "Devices" at the bottom of the screen and then tap "Echo & Alexa" at the top of the screen.

3. Tap the device you want to use Follow-up Mode with.

4. Tap "Follow-up Mode" and then turn it on by swiping the button to the right.

Whether or not you choose to use Follow-up Mode, here are the most common and important commands you can use with Alexa.
