This study examines the structural models of Lithuanian plosive consonants in intervocalic, word-initial and word-final positions. The research material consists of 24 sentences read three times by 6 native speakers. The results show that the plosive consonants can be composed of one to three phases, and the most frequent and common models are the closure with a burst release, which might be followed by a different degree of frication.

Studies on the rhythm of living Baltic languages are scarce (especially comparative ones) and their conclusions are usually ambiguous or even controversial. The aim of this research was to determine the values of the acoustic correlates of Lithuanian and Latvian languages and to compare them with the values found in other languages, identified by researchers as belonging to particular rhythm groups. The empirical material of this study consisted of 5 Lithuanian and 5 Latvian native speakers reading Aesop's fable The North Wind and the Sun in their respective native languages. The acoustic analysis of the audio recordings was performed using Praat and Correlatore applications. The analysis showed that the values of the acoustic rhythm correlates in both Baltic languages were found unequal. Nevertheless,according to the studied acoustic correlators, Lithuanian belongs to stress-timed languages, while Latvian is closer to syllable-timed languages.

This paper presents our research in preparation to compile a Lithuanian intonation corpus. The main objective of this research was to discover characteristic patterns of Lithuanian intonation through clustering of pitch contours of intermediate intonation phrases. The paper covers the set of procedures that were used to extend an ordinary speech corpus to make it suitable for intonation analysis. The process of intonation analysis included pitch extraction, pitch normalization, estimation of the representative frequency of a syllable, measurement of an inter-phrase similarity, k-means phrase clustering, and visualisation of clustering results. These computational procedures were applied to 23 hours of read speech containing 41417 phrases. The clustering results revealed some interesting intonation patterns of Lithuanian that could be related to the well known linguistic-prosodic phenomena. Language-independence is an important feature of computational procedures covered by this paper. If speech waveforms and the knowledge of phone and phrase boundaries are given, these procedures can be used for the analysis of intonation of other languages.
