What makes a charismatic speaker? The present study extends this question into the prosodic dimension of voice quality. We analyzed various F0, LTAS and LTF long-term spectral characteristics from 12 L2 speakers of English who were recorded while giving entrepreneurial speeches.
The results of the acoustic analysis were correlated with indirect judgments of the entrepreneurs'charismatic performancesby 98 listeners. The findings are discussed with respect to their implications for measuring and training charismatic speech, traditional rhetoric statements and the definition of charisma.
