Using simulated telephone dialogues in which the subject makes repeated corrections of a street address digit sequence, articulatory and intonational patterns are observed for four native speakers of American English. The articulatory patterns are recorded by the computer-controlled x-ray microbeam system at the University of Wisconsin. Effects of the contrastive emphasis, which are assumed to be associated with the digit to be corrected, are examined. Effects of emotional involvement of the subject are observed in a situation where the experimenter, as the dialogue partner, persistently cites an incorrect digit sequence, asking for confirmation/correction by the subject.
