Abstract: An information processing method includes a reading step, an acquisition step, a conversion step, a determination step, and a display control step. In the reading step, first character information on a character of a teaching material is read. In the acquisition step, a read-aloud sound relating to a first user's voice when the first user reads aloud the first character information is acquired. In the conversion step, the read-aloud sound is converted into second character information on a character. In the determination step, based on the first character information and the second character information, a matching point between the first character information and the second character information is determined. In the display control step, when there is the matching point, the matching point is displayed in the first character information in a different display manner from a display manner of the first character information.
