Abstract

The present invention is intended to perform text-to-speech conversion by replacing URLs and electronic mail addresses included in the text data of electronic mail by registered predetermined words. A mail watcher application control section executes the processing for converting electronic mail received by a MAPI mailer into speech data. The mail watcher application control section outputs URLs and electronic mail addresses included in the text data of electronic mail supplied from the MAPI mailer to a URL and mail address filter to replace them by registered predetermined names. Of the entered texts, the URL and mail address filter compares the URL or mail address included in the entered text with those registered in the URL and mail address table. If a the URL or mail address of the entered text is found matching, the URL and mail address filter replace it by the registered name and outputs it to the mail watcher application control section.
