Pronunciation actions are like any other body actions, which follow the same process of initiating, acting and ending. Academic studies show that the underlying default oral postures and mechanics across languages are significantly different. So suffice it to say that a better pronunciation training program should be able to address the process of initiating, acting and ending of every complete pronunciation action. But if we look at most of the pronunciation materials or training programs today, they are no exception all teaching you the tongue and lips positions, which only address the ending of the pronunciation action processes.
