In my opinion you are wrong. We CAN speak like normal speakers do. One can discuss a lot about causes of stuttering but when a lot (or most) stutterers can read aloud alone, whisper, talk to kids or animals, talk in unison etc without stuttering they have already proved that they CAN speak like normal speakers.Stop planning your words, speak immediately when you get the urge and if you start thinking words, say something else. I don't know how you think speech is supposed to be, but speech is supposed to be just as automatic as your breathe and you cannot use your wrong part of brain to speak.
