Medical electronics II: Seeing speech in real time: The deaf can now view tongue, jaw, and other vocal-tract movements on a CRT display

Kim is a 3 1/2-year-old profoundly deaf girl who spoke with the high-pitched, effortful sounds so often characteristic of the deaf. With a speech-feedback system called the dynamic orometer, however, she soon mastered speech-reproduction patterns and also began to talk in a relaxed way, in a pitch lowered to the normal childhood range. The orometer is being developed at the University of Alabama in Birmingham.
