Abstract: The operating system or application program generates events captured by an event handler mechanism that, in turn, invokes message assembler and graphics assembler modules. The message assembler constructs pseudo-random sentences or notification messages based on the type of event captured and optionally upon selected state variables. The message assembler supplies text strings to a text-to-speech engine. A linguistic database containing a lexicon of predefined words supplies text data that the message assembler concatenates to form the text strings. Text strings are assembled and optionally tagged to alter the message, speaking voice and inflection based on the nature of the message and its context. Graphics elements are assembled by a graphics assembler in response to the event handler and based on optionally supplied user-defined graphics parameters.
