Abstract
A research presentation integrates slides and speech. If these two aspects do not represent the same intention, the presentation will probably fail to effectively explain the presenter’s intention. This paper focuses on the representation of the critical contents in a presentation. In an effective speech, the speaker adds more intonation and stress to emphasize the importance of the slide contents. Audiences recognize that important contents are those that are explained in a stronger voice or that are said after a short pause. However, in ineffective speeches, such voice effects do not always correspond to the important contents that are indicated by slides. On slides, the important contents are represented by levels of text indentation and size, color, and animation. This research develops a presentation speech support system that estimates important contents from slides and voices that might be recognized by audiences and extracts numerical differences. In addition, the system provides comments and feedback to improve speeches.
Highlights
Scientists and researchers often explain their ideas and work using presentation support tools such as Microsoft PowerPoint
The emphasis-intentions extracted from the slide area were inappropriate for other subjects who wanted to emphasize the texts written in the figures
This paper proposed a novel method for improving presentation speech techniques by representing emphasis-intentions for important slide contents
Summary
Scientists and researchers often explain their ideas and work using presentation support tools such as Microsoft PowerPoint. In addition to slides that visually represent their contents, we speak about and explain them by providing verbal explanations as well as gestures and body language. The intonation and the speed of verbal explanations emphasize the important contents in the slides and provide a rhythm for the speech. Since many presenters fail to effectively express themselves through their speech, including the importance of slide contents, they fail to successfully explain their work or ideas to audiences. Emphasis-intention is our term for the motivation that emphasizes important contents. The objective of our research is to support presenters so that they can give speeches that represent the emphasis-intentions of important slide contents. We are focusing on research presentations in the computer science field, where slides contain the main ideas of topics and the oral speech adds complementary explanations
