Thanks to Kevin from Demented Elf Productions, which gave me the right to use their voice files, i quickly developed a small plugin for the current time.
Unzip files to RadioDJ directory and restart rdj. A new action will be available for events in plugin actions. Also if the plugin is assigned to a button in main window, when pressing that button, will announce the current time.
The plugin is using the sweeper sound-card and it's acting like a sweeper fading down the main player for the duration of the announcement.
