If you've ever done voice prompt recordings for a phone system, voice cloning would be super helpful for doing one off tweaks, especially if you have to record a bunch. Instead of rerecording 20 messages, which can sometimes take hours, you can use a clone of your own voice to make the necessary modifications. My friend does a lot of recordings as part of his job and when I showed him the Adobe voice editing preview he got really excited. It has the potential to make tweaks a lot easier, less time consuming, and reduce voice strain.
