SayO'Clock is a talking digital clock which speaks 'on demand' or according to a schedule, using either pre-recorded 'Real Speech' or Text To Speech (TTS). It informs you how many TTS engines you have installed in your system, and the name of the TTS voice that shall be speaking. You can swiftly change from one voice to another, as well as the application's mode of operation ('Announce Time' or 'Alarm' mode).
