Have you tried Delayed Auditory Feedback? An app for that is free. Experiment with that and see if it helps. To get a DAF device that is optimal for you, you would need to find an SLP who has experience with those devices. This is a company that sells them. https://speecheasy.com/delayed-auditory-feedback/ But I suggest downloading an app and try it first, might work well enough just using your phone and an earbud, so you don’t have to spend the money.
