About the quantity of Lithuanian approximant lateral, nasal and trill consonants

Summary/Abstract: The acoustical properties of Lithuania consonants have been very little researched. The aim of this work is to investigate at least the tentative relations of the duration ofLithuanian approximant lateral, nasal and trill consonants. Investigations are based on a coherent text fragment recorded by V. Širka (about 1 h 40 min. record, containing about 60 thousand sounds). The coherent text was chosen on purpose to define differences of duration, exist-ing in a real usage. The duration of the consonants was set automatically, recording the sounds with speech identification equipment (HTK). The duration data was processed statistically. In this paper it is analyzed if the duration of consonants depends on palatalization, place of articulation, if the duration differs when it is diphthong and if the accent has an influence on its duration. Tentative results show thatpalatalized consonants approximants are a little bit longer than hard consonants in term of their duration. Aplace of articulation of all these consonants is quite close, therefore obvi-ous duration differences were not observed. From the results a tendency can be noted, that diphthongs are longer than monophthongs. However, the results should be revised. As it was expected, stressed part of diphthong is longer than of that unstressed.
