The Voice Synthesizer (text-to-speech) allows you to create automatic announcements that will be read by the program. You can specify the text to be read by the program or specify the path to the file with the text. The file or text can contain XML tags according to Speech API: https://msdn.microsoft.com/en-us/library/ms717077(v=vs.85).aspx
In the synthesizer settings, you can select the voice and the reading speed. It is recommended to choose the voice according to the text language. Additional voices can be installed through the Windows Control Panel.
The text can contain variables, such as weather data and current date/time
%M - month
%D - day
%dw - day of the week
%h - hour
%m - minutes
%s - second
