There are options to play certain segments of the conversation which illustrate interactional synchrony in the communication. Dialogue may be viewed by dialogue line or by timeline. Selected segments may be played in head or long shots and at normal or slow forward. In slow motion, the voices are still audible so that students may study verbal and nonverbal synchrony. The Learn the Roles section permits one or the other role to be blocked out as an aid to students in the process of memorizing their lines.
Students play a line from the original dialogue.
The intonation curve of that line is shown on the screen. A speech analysis program plots the student's intonation curve below that of the native speaker. This is used later in the learning process when the student has more or less mastered memorization, phonetics, and nonverbal features of the conversation. The original dialogue plays but shuts off the audio track of the speaker whose role the student is playing. Mastery of rhythm and pacing is the objective here.
