Abstract
Filled pauses (FPs) have proved to be more than valuable cues to speech
production processes and important units in discourse analysis. Some
aspects of their form and occurrence patterns have been shown to be
speaker- and language-specific. In the present study, basic acoustic
properties of FPs in Polish task-oriented dialogues are explored. A set of
FPs was extracted from a corpus of twenty task- oriented dialogues on the
basis of available annotations. After initial scrutiny and selection, a
subset of the signals underwent a series of pitch, formant frequency and
voice quality analyses. A significant amount of variation found in the
realisations of FPs justifies their potential application in speaker
recognition systems. Regular monosegmental FPs were confirmed to show
relatively stable basic acoustic parameters, which allows for their easy
identification and measurements but it may result in less significant
differences among the speakers.
