AutoDialer is a utility designed to automatically dial numbers at a
specified time
and say something through Speech Manager. The computer dials and speaks
through the computer's built-in speakers, eliminating the need for a modem.
Version 1.1 adds several new options when dialing, automatically converts
letters to numbers, and allows you to choose how many times to repeat the
message.
