CHARACTER STRING DISPLAY SYSTEM, CHARACTER STRING DISPLAY METHOD, AND STORAGE MEDIUM

It is an object of the invention to provide a character string display system, a character string display method, and a storage medium that can determine a display time according to character string display times in the past to thereby determine a display time corresponding to speed of reading and understanding a character string of an individual who reads the character string. The character string display system is characterized by including: a display time determining unit for determining a display time for a display character string on the basis of a reference value; a display unit for displaying the display character string for the display time determined by the display time determining unit; an operation unit for detecting predetermined operation performed by an operator while the display unit displays the display character string; and a reference value changing unit that, when the operation unit detects operation of the operator, extends or reduces a time, during which the display unit displays the display character string, and changes the reference value according to the extension or the reduction of the time for displaying the display character string.
