Experiments in Speech Perception Interactive exercises also demonstrate experimental techniques.
Students can easily perform speech perception experiments using synthetic speech.
This screen illustrates a stimulus continuum, such as would be used in an identification or discrimination experiment. The screen shows spectrograms of seven stimuli. A student can play a stimulus by clicking the loudspeaker of the corresponding spectrogram. A variety of different experiments in the course use the same stimuli, playing them alone or in combination. After analyzing the data from the student's experiment, a discrimination function is plotted on the screen, showing the percentage of times that each pair of adjacent stimuli was judged different.
