Using speech technology to promote increased pitch variation in oral presentations

This paper reports on an experimental study comparing two groups of seven Chinese students of English who practiced oral presentations with computer feedback. Both groups imitated teacher models and could listen to recordings of their own production. The test group was also shown flashing lights that responded to the standard deviation of the fundamental frequency over the previous two seconds. The speech of the test group increased significantly more in pitch variation than the control group. These positive results suggest that this novel type of feedback could be used in training systems for speakers who have a tendency to speak in a monotone when making oral presentations.
