[https://www.fromthesidebar.com/2011/03/03/the-kings-speech-a-trial-lawyers-stutter-2/](https://www.fromthesidebar.com/2011/03/03/the-kings-speech-a-trial-lawyers-stutter-2/) per this lawyer he feels that his stutter is actually an advantage as it forces the judge and jury to do two things - one take sympathy (this is such an underrated skill to be able to invoke sympathy in a jury but even more so in a judge) and two it forces the judge and jury to listen more closely to your argument. Finally I would add that while I have not known any trial lawyers with a stutter but i have known 2 one very successful in securities law one corporate and one with the SEC.
