The study consisted of sonagraphic analysis of pronoucing the ra-line of Japanese kataka-na, "ra ri ru re ro" under two different con-ditions, namely normaly at first and then in such a way by fixing the tip of the tongue at the root of the lower incisors firmly wi-thout movement. The records of these two types of dilivery were compared to each other.

Under normal conditions the pronounciation of Japanese "r" contains two bars whose mean frequencies are approximately 0.5 and 1. 5kc respectively, the beginning of the vib-ration being sharply defined. Under the fixed condition there was a diminishing effect on the 1.5kc bar and the 0.5kc bar was not sharply defined in its beginning but under went a change of a slow build-up.
