A setting window that is displayed when a mail tab is selected includes check boxes for selecting items to read when an electronic mail is read, and a check box and a drop-down list box for setting automatic checking of electronic mails. Contents corresponding to checked boxes among the check boxes are converted into speech data. Furthermore, the contents corresponding to the checked boxes among the check boxes, except for the body of the electronic mail, are used for generating a title to be added when the speech data is output to an external apparatus, etc. If none of the check boxes is checked, a predetermined character string is set as a title.
