Lessons learned from Steve Jobs' way of presenting

Steve Jobs has undoubtedly been a genius in successful product presentations. His charismatic style is a great example for speakers in any setting.

How did he manage to convince his audience of the superior properties of the Apple products even when competitors offered comparable products and services? In establishing a first-ever acoustic profile of Steve Jobs, Oliver Niebuhr and Alexander Brem of SDU Innovation and Design Engineering together with Jana Voße have published an acoustic-prosodic analysis of Steve Jobs tone of voice. The increasingly close interrelation of computers and behavioral characteristics like human speech builds the basis for this unique piece of research. Their article gives specific advice how speakers can improve their charismatic impact, which has direct implications for practice and research alike.

In analyzing about 4000 syllables and 12,000 individual speech sounds from two product presentations, the authors investigate voice pitch, loudness, duration, accents and rhythm and derive that variability is essential for charismatic speech. Short utterances, short pauses, variable and audience-tailored pitch and accent patterns, and the lack of disfluencies lead to a more charismatic tone of voice. Although this study does not take cultural and social dimensions or melodic systems of other languages into account, it builds a solid basis for future research where progress and diversification in the computer-based analysis of human speech behavior will move computers even further to the centre of the speech sciences.
