Canonical and actual speech and articulation rate throughout spoken dialogues
Línková, Alena ; Skarnitzl, Radek (advisor) ; Volín, Jan (referee)
Speech tempo and its variability in Czech have been the subject of many studies, but most of them have primarily focused on monologues. In this bachelor thesis, we focus on speech tempo variability in dialogues, as well as on different ways of measuring speech tempo and how that can affect the values obtained. The thesis includes a theoretical section that summarizes current knowledge regarding speech tempo, different ways of objectively measuring it and factors affecting its values, perception of speech tempo and factors that affect it, pauses, and the specifics of speech tempo in dialogues. In the practical section, we analysed the recordings of 13 speakers participating in a television political debate. We measured articulation rate in prosodic phrases and speech rate in clauses and thematically unified paragraphs, as well as local rate in the initial, medial, and final thirds of these dimensions. We measured syllable (syll/s) and phone rate (ph/s), and canonical and surface (syllable) rate. We found statistically significant differences between tempo values in thirds of clauses (syll/s) and prosodic phrases (ph/s), but not in paragraphs (syll/s). The effect of the length of a prosodic phrase on both syllable and phone rate values was, however, found not to be statistically significant. Powered by TCPDF...
