Amazon has updated Alexa with several new powers that make it a more usable and fully-rounded voice assistant. First, Alexa gains a "Follow-Up Mode" that makes interacting with the assistant more natural. Once enabled, Alexa will listen for 5 seconds after completing an exchange for follow-up requests. The idea is to negate the need to repeatedly use the "Alexa" or "Echo" wake phrases. People will be able to wake an Echo device once, complete an interaction, and then immediately follow it up with a second request/interaction without using the wake phrase again. According to CNET, the blue ring on Echo devices will remain illuminated during this 5-second listening period. If no request is made, the Echo device will go back to sleep. Separately, TechCrunch reports that Amazon has brought Alexa voice calling to iPads, Android tablets, and Amazon-branded fire tablets. Alexa on Echo devices has been able to place voice calls for several months. Tablet owners can now initiate voice/video calls and send messages with Alexa on the slate of their choice. Amazon Fire tablets further gain the ability to act as intercoms, called Drop-In Mode, for talking to other Fire devices on the same WiFi network. Both Follow-Up Mode and voice calling on tablets need to be activated within the latest version of the Alexa app on mobile devices.
