I've noticed that a very few people--native speakers of English--who have a habit, analogous to a lisp, of replacing dental sounds with what hits my ear as interdental sounds. Words like 'later' come out like 'layther'. I've just been calling it 'lazy tongue,' but I'm hoping there's a formal and less derogatory descriptor. Dr. Mehmet Oz's speech is a good example of this.
