Amazon's new Fire HD 8 tablets let you use Alexa without speaking
 

Amazon is revamping its 8-inch tablets for the first time in two years, but their biggest improvement might rest in the software. The company has introduced new Fire HD 8 models that introduce a "Tap to Alexa" feature. You can not only control the assistant exclusively using touch, but pair with a supporting Bluetooth switch or use text-to-speech to have commands spoken for you. This is particularly helpful for people with speech and mobility disabilities, but could also be useful if you just don't want to speak (say, to avoid waking your baby).
