Amazon's update comes at a time when Google is anxious to take over the virtual assistant space. Along with the Google Pixel phone, which offers the aptly named Assistant built right in, the upcoming Google Home is set to release in early November. Considering all Android devices, tablets and phones come with Google's voice services by default, getting Alexa onto the Fire tablets keeps Amazon competitive. For now, Amazon's Echo still remains the always-listening virtual assistant to beat, but Google may have something to say about that when Home comes on November 4.
