Alexa on Fire TV has gradually improved since it first debuted last September; Tuesday's update adds television controls and app-launching capabilities.
While the new features are not immediately available, Amazon will roll these out via software updates over the next few weeks.
Among the key new features are Fire TV app-launching capabilities and the option to ask Alexa to play content from Amazon Video and any add-on subscription content, as well as the capability to find movie showtimes at nearby theaters, read Kindle ebooks, and local business search.
The Fire TV version was really no more than just another Echo speaker in your system when it launched in September, although Amazon added smart home support two months later.
Consider it a move to put it on par with compeitors: Apple TVs already have Siri integration, and the Roku 3 and 4 have similar voice-enabled functionality.
Besides the Alexa improvements, Amazon also made a move Tuesday to improve content availability.
