You can save a production you like and then let the student compare pitch on a new stimuli with his own best production by saving the production on the upper screen and then using the lower screen to capture subsequent speech samples.
You can compare pitch statistics for two productions and then save or print these values.
It is very easy for students to see intonation on a computerized pitch program. The curve of the line varies with pitch changes. It is flat when a student has a monotone voice.
Computerized visual feedback instrumentation not only allows the instructor and student to see a line indicating pitch level, but in most programs you can also compute and print the statistics to get objective measures of pitch.
