AN ANALYSIS OF SPECTRAL ATTRIBUTES, CHARACTERIZING THE INTERACTION OF LITHUANIAN VOICELESS VELAR STOP CONSONANTS WITH THEIR PRE- AND POSTVOCALIC CONTEXT

Abstract

This work describes an investigation of spectral properties of the voiceless velar stop consonant [k] of Lithuanian. Investigations are based on two Lithuanian corpora: the isolated word corpus VDU-ISO4 and the corpus of short connected phrases VDU-TRI4. Investigations showed that spectra of a plosive [k] exhibit maxima at a frequency corresponding to the second formant of the vowel following plosive [k] and a context independent maximum at 4000 Hz. Properties of these maxima were investigated separately for male and female speech, and for long and short vowel contexts. Results are useful for automatic speech recognition.
