RESEARCH WAS CONDUCTED IN THE DEVELOPMENT AND TESTING OF A SELF-MONITORING METHOD OF TEACHING PROPER INTONATION AND INFLECTION PATTERNS TO THE DEAF. THIS TEACHING METHOD INCLUDED USE OF A VISUAL DISPLAY WHICH IS BASED ON PITCH INFORMATION DERIVED FROM A LIVE SPEECH SIGNAL. FOUR PROFOUNDLY DEAF CHILDREN WERE THE SUBJECTS FOR THE EXPERIMENT. A SPEECH EXTRACTOR (OSCILLOGRAPH) WAS USED TO VISUALLY DISPLAY VOICE SOUNDS PRODUCED BY THE INSTRUCTOR AND SUBJECTS. INSTRUCTION IN VOWEL SOUNDS WAS AIDED BY HAVING EACH SUBJECT TOUCH THE INSTRUCTOR'S THROAT WHILE AT THE SAME TIME TOUCHING HIS OWN. IN ADDITION, DIAPHRAGMATIC BREATHING AND BETTER SITTING POSTURE WERE INTRODUCED. SOME OF THE CONCLUSIONS REACHED WERE--(1) THE CONCEPT OF TEACHING PITCH VARIATION OR PITCH INFLECTION TO DEAF INDIVIDUALS USING A SELF-MONITORING DEVICE SUCH AS THE PITCH EXTRACTOR IS POSSIBLE, (2) VOLUME AND DURATION ARE THE MOST SIGNIFICANT FACTORS IN THE PRODUCTION OF THE VISUAL DISPLAY, (3) KNOWLEDGE OF THE SUBJECT APPEARS TO BE IMPORTANT FOR SUCCESSFUL PERFORMANCE, AND (4) ATTENTION AND INTEREST SPANS ARE IMPORTANT VARIABLES TO BE CONSIDERED IN THE TEACHING PROCESS. FURTHER RESEARCH WAS RECOMMENDED WITH RESPECT TO INCREASING THE NUMBER OF LESSONS, USING DEAF CHILDREN WITH ABOVE AVERAGE IQ, AND PERFECTING THE EQUIPMENT AND TECHNIQUES. (AW)
