YouTube is testing a new feature. It allows video creators to respond to user comments with voice messages. This can make communication between creators and audiences more personal.
Details
At the moment, this feature is available only to a limited number of users and works only in the mobile application. Users in the test group can use the new feature by clicking on the sound wave icon when replying to a comment. At the same time, you need to press record a voice reply and then publish such a voice reply as usual.
