For a variety of reasons, it can be useful to keep the audio that someone has in a video, but replace the person's voice with AI (poor audio quality in the video, privacy considerations, etc.). Right now the only way to do that is go in, type out what the person is saying, and then assign an AI voice. Unfortunately, that takes a great deal of time. It would be lovely (and time-saving!!!) to be able to simply highlight that section of text and replace it with an AI voice.
