Naturally, all of these experimental features could soon be brought in to the regular version of YouTube in the near future if the company chooses to do so. For now, among the experimental features that are offered include Watch On Home, Voice Search On Web, and Filter by Topic.
The Watch On Home Screen offer users the ability to seek videos without leaving their Home screen. As for the Voice Search On Web feature, users will be able to search for videos by using voice commands. Lastly, the Filter by Topic feature allows users to filter topics in three new languages. It is worth noting that the Watch On Home Screen feature will only work on iOS devices. As for the other two, both features will work on the web version of the video streaming platform.
