A system which presents a user with a sequence of prompt messages and stores user responses to at least selected ones of these prompt messages, classifies the stored user responses in a first category when the user responds to a first one of the prompt messages and not to a second one of the prompt messages, and classifies the stored user responses in a second category when the user responds to both the first and second prompt messages. In addition, this system classifies the stored user response in a third category when the response includes any one of a plurality of code words, and in a fourth category when the user response includes none of these code words. An alternate embodiment classifies stored user responses in accordance with the duration of the response to a selected prompt message. The described classification techniques materially enhance transcription efficiency.
