9. SUMMARY OF RESEARCH RESULTS:

	WE DEVELOPED A PORTABLE SPEECH ANALYSIS SYSTEM FOR JAPANESE DIALECT 
SPEECH IN HUMAN SCIENCE.  THE SYSTEM IS PORTABLE IN AN ACQUISITION PLACE, A 
LABORATORY, A LECTURE ROOM AND SO ON.  A HARDWARE OF THE SYSTEM CONSISTS OF 
A NOTE TYPE PERSONAL COMPUTER AND A SMALL SPEECH INPUT-OUTPUT DEVICE.
	THE SMALL DEVICE IS NEWLY DEVELOPED FOR THIS STUDY.  AND THE DEVICE 
CONSISTS OF TWO TYPES OF LOW PASS FILTER, 16 BIT ANALOG TO DIGITAL CONVERTER
AND DIGITAL TO ANALOG CONVERTER,  FIRST-IN-FIRST-OUT MEMORY, LINE AMPLIFIER 
AND SO ON.  THE FIFO MEMORY IS AVAILABLE FOR LONG TIME SPEECH WAVE ACQUISITION.
	THE ANALYSIS FUNCTION OF THE SYSTEM CONSISTS OF MEASUREMENT OF LONG 
TIME PERIOD OF SPEECH WAVE, FORMANT FREQUENCY LOCUS, FUNDAMENTAL FREQUENCY 
LOCUS, SOUND SPECTRUM GRAPH, SPEECH POWER SPECTRUM, LINEAR PREDICTION SPECTRUM,
PSEUDO VOCAL TRACT AREA FUNCTION, SHORT PERIOD WAVE POWER, ZERO CROSSING RATE 
AND SO ON.
	THE SYSTEM IS INTERACTIVELY OPERATED MENU DRIVEN METHOD WITH COMPUTER 
MOUSE, SO SPEECH ANALYSIS IS VERY EASY FOR RESEARCHERS OF HUMAN SCIENCE.
