How does a TTS or highlighting system work for learning?

Abstract

There are individual differences in human cognitive function, and that is a widely known fact. A hypothesis we made is that; giving both visual and audio stimuli may make it easier for people to catch information. In this research, three indicators are set consisting of memory, understanding, and concentration for an experiment. The difference in learning effect due to the reading situation was measured. We concluded that a Text-to-Speech (TTS) and the highlighting system can help reading in some cases.
