Acoustic analysis of the length of the consonants in the Northern Žemaitian dialect has shown that:
a) the length regularities are common to the Northern Žemaitian and Standard Lithuanian;
b) the length of the consonants is determined by the activity or passivity of vocal cords at the time of articulation;
c) the length is very closely correlated with the manner of articulation;
d) the place of articulation and the softness or hardness do not have any noticeable effect on the length of the consonants.
