Sounds like HELP: the use of voice for procedural instructions in GUI HELP
Nina Reeves, Stephen Mills, Jan Noyes · 2002
During a study considering the usability of a graphical user interface (GUI) for discretionary, intermittent users, the on-line HELP was found to be unsatisfactory from the point of view of flexibility and learnability. The HELP system for a spreadsheet package was rewritten to incorporate spoken, procedural instructions and the usability assessed in situ by considering the task completion rates and times together with user satisfaction. A complex picture emerged suggesting a follow-up study considering the learning styles of the users. The results reported here are part of a larger case study.
