摘要

An auditory user interactive interface to an application program being installed in the computer controlled system. A routine in an object, in an application program being installed in the computer controlled system for providing an auditory user interface to the program in combination with auditory means for offering the user of the computer controlled system the auditory user interface during installation of said application program, and responsive to the selection of the auditory interface provides the auditory user interface during said installation of the application program. The functional object in the application program being installed includes the routine for providing the auditory interface preferably implemented in Text to Speech (TTS) functions together with an implementation for determining whether the computer controlled system receiving the application program includes a TTS engine compatible with the TTS functions in the application program and a routine for installing a TTS engine compatible with the routine when the computer controlled system does not include the TTS engine.
