I don't think there is.
You could always try an audiologist, therapist, maybe even a hypnotist. Sometimes, when it is not caused by an actual physical problem but a psychological one, as if someday you've been harshly interrupted or or were ordered not to talk, etc. you can do a regression to when it all begun and cure ir from there. Just be aware, a regression involves very deep feelings and lots of emotions.But, again, I'm not sure if your problem is psychologial or physical, and maybe those could help, but with a spell? Nah.
