Because repetitions, prolongations and speech blocks (and interjections, and meaningless sounds) are disfluencies (externally monitored). Speech errors are internally monitored. Perceiving speech errors (such as, anticipation) can lead to stuttering (Postma) * [Screenshot](https://i.imgur.com/8G0ugFS.png): Speech errors in the speech plan are internally monitored (Usler)
