Voice Quality and Dialogue Structure

Kathrin Classen, Wolfgang Wokurek

Universität Stuttgart, Germany

The primary aim of this acoustic study was to investigate spectral properties of first and repeatedly mentioned word tokens in task-oriented dialogues. Secondary aims were to assess the influence of word position in the phrase, role of speaker in the dialogue, and familiarity between participants, on these properties. The acoustic measurements comprised automatic spectral analysis of the glottal parameters open quotient (OQ), glottal opening (GO), skewness of glottal pulse (SK), rate of closure (RC), amplitude of voicing (AV), and completeness of closure (CC). Results of our Map Task experiments indicate significant spectral differences in the glottal parameters OQ, SK, RC, AV for the variables familiarity of participants and role of the speaker in the dialogues. First versus repeatedly mentioned word tokens differ significantly only in OQ and RC. Furthermore, no effects were found for the variable word position in the phrase.
