Measuring liveliness in presentation speech

Rebecca Hincks

This paper proposes that speech analysis be used to quantify prosodic variables in presentation speech, and reports the results of a perception test of speaker liveliness. The test material was taken from a corpus of oral presentations made by 18 Swedish native students of Technical English. Liveliness ratings from a panel of eight judges correlated strongly with normalized standard deviation of F0 and, for female speakers, with mean length of runs, which is the number of syllables between pauses of >250 ms. An application of these findings would be in the development of a feedback mechanism for the prosody of public speaking.
