Visitors use an electrolarynx to speak without using their vocal cords. They can also feed sound from the electrolarynx into four transparent, cast plastic models of a human throat and mouth pronouncing vowel sounds - OH, EE, AH, and EH. The sounds they make appear as waveforms on an oscilloscope and as a real-time spectrogram. For more images and information on the Wild Music exhibit, visit www.wildmusic.org.
