I've always wondered how Barbara Walters managed to break into that industry with such a bad speech impediment.
Tom B also has a speech impediment. There are quite a few people in the news (on CNN there are a couple people) with speech issues.
I have a theory about that. It goes something like this....people with speech problems generally take speech therapy to overcome it (my son did). If they took broadcast journalism in college then they also received speech therapy of a sort....in each of these instances, one of the tools used to correct the impediment is public speaking, pulling radio gigs in college, etc. I think they get so used to doing it, a profession as a talking head seems natural.
Having said that, I find it distracting and won't listen to anyone on tv with a lisp or speech impediment. Drives me bonkers.
