To enable a non-visual user to freely and easily control a hypertext by accessing a link destination according to the detection of the user input and based on the link destination information corresponding to a specified link keyword.

A focus control part 129 compares the pointer information on a voice synthesis pointer 169 and a character string list 131 with the link head flag information and specifies the information on a link destination 311 corresponding to an area that is currently read aloud. The part 129 stores the pointer information in a focus pointer 139 for the specification of the destination 311. The link destination information can also be directly stored. If the key input showing a jump to the destination 311 is detected while such a read- aloud operation is carried out, the link destination information corresponding to the pointer 139 can be specified.
