Abstract
Abstract A system for speech training is described which stores and displays speech parameters (pitch, intensity, etc.) on a television screen as a trace or line. Two parameters from the same speech signal (for example, pitch and intensity) are stored and displayed simultaneously, one on the lower half of the screen and one on the upper half of the screen. The same parameters from the voice of a speech therapist can be displayed along with those of a trainee. The therapist''s and trainee''s parameters are separated using black traces for the trainee, and white traces for the therapist on a grey background. Both the therapist''s traces and the trainee''s traces may be independently moved about the screen so that they can be overlaid for direct comparison, thus assisting trainees, especially the deaf, to improve their speech. The digital system produces a visible trace when the sum of the line count number plus the signal value equals a predetermined value. Trace-broadening indicias are formed by a plurality of sum values.
