Abstract [eng] This research aims to answer the old and interesting question: which exactly measurable prosodic features constitute the audible distinction of Lithuanian syllable tones. The main task of our investigation was to reveal whether or not there is a correlation between the quantity of the accented vowel and the velocity of change of the vowel pitch (a prosodic feature also known as pitch movement or pitch velocity).The mathematical method applied in this research demonstrated considerable influence of vowel duration on the relative pitch velocity: the tone rises or falls relatively slower in longer vowels and more intensively in shorter ones. Establishing this dependence opens up new perspectives of interpreting Lithuanian syllable tones. Our more general conclusion is that using relative values derived from measured prosodic parameters is a more reliable method to demonstrate the distinction of syllable tones than to use absolute values. Our hypothesis was also confirmed by statistical analysis. The material for this research was collected from the North Žemaitian dialect of the Lithuanian language. Our analysis reveals that there is a demonstrable distinction between the circumflex and the acute tones in this dialect: the circumflex can be defined as a level tone with relatively slower pitch movement, and the acute, as a steep, rude tone with more intense tonal velocity.
