Google is introducing more AI features gradually and after the introduction of the bumper ads few months ago, we have now the possibility of adding a voice-over in any video from our account or Youtube.
As you can see in the screenshot, you just need to select a voice and then write the script that the voice will reproduce.
To be honest, some voices are quite natural haha and you have multiple tones of voice.
This can be a good feature to give a different approach to all these videos with only transitions and headlines which normally convert way worse than UGC videos.
