Amazon Fire 7 and Fire HD 8 tablets are getting hands-free Alexa feature
Currently, to activate Alexa on the Amazon Fire 7 or Fire HD 8, you pick up either tablet and tap the Home button until a blue line appears. At that point, you can ask Alexa to handle your request. But once those two slates receive the new feature, you just say "Alexa..." and continue by telling the virtual assistant what you want it to do.
The Fire HD 10 can summon help from Alexa hands-free, with the screen on or off, and the tablet on battery. However, if you are using the Fire 7 or Fire HD 8 on battery power, the screen must be on to use Alexa hands-free. If either one of these two tablets is plugged in, the screen doesn't have to be on for you to ask Alexa to do something for you.
The new feature is being rolled out to the Fire 7 and Fire HD 8 starting this week. If you own either tablet, keep an eye peeled for it.
