Roku OS 10.5 adds better voice support, 5.1 Roku speaker configurations
 

You won't need Roku's new Streaming Stick 4K to take advantage of its latest software features. The Roku OS 10.5 update, which will roll out to players and TVs in the next few weeks, will be jam-packed with features to make your streaming life easier. There's expanded Roku Voice support, which will let you ask players (with supported remotes) to start playing content from Netflix, Spotify and most other channels. And the company has added a Live TV Channel Guide to help find free TV content (so far there are more than 200 live channels to sift through).
