Our correction technique is based on a step-by-step transition from situational to contextual speech. We start from the easiest situation when both objects and actions to be described by the child can be directly contemplated (accompanying speech). In this situation stammer can be easily avoided after several hours of training. Then the child is stimulated to speak about absent object and to describe his past actions. At the next stage the child discusses his intentions, plans, as well as his experience using more and more complex grammar and words whose meaning may be clear only from a verbal context. Such series of exercises clears ground for a well-planned and smooth speech.
