In this type of comparison, the program will cycle through all the comparisons specified in the complex scheme.
Observers can score overall sound similarity, or score syllable by syllable. In the latter case, each syllable in spectrogram 1 (the upper spectrogram) msust be linked with the most similar syllable in spectrogram 2.
As in the Simple visual comparison, the controls in the top-left of the pane control the appearance of the spectrograms, and observers may also play-back whole sounds, or individual syllables to aid with their comparisons.
