METHOD AND APPARATUS FOR ANALYSING A PITCH METHOD AND SYSTEM FOR DISCRIMINATING A CORPORAL PUNISHMENT AND COMPUTER READABLE MEDIUM STORING A PROGRAM THEREOF

摘要

PURPOSE: A method for analyzing a pitch and an apparatus thereof, and a method for discriminating four constitutions and a system thereof are provided to discriminate a constitution of a speaker by using an analyzed voice of the speaker. CONSTITUTION: An A/D converter(100) converts an analog audio signal provided from a microphone(90) into a digital audio signal. A pure audio signal extracting unit(200) low-pass filters the converted audio signal, extracts a signal over a predetermined threshold for extracting a pure audio signal. A time domain analyzing unit(300) analyzes a waveform of the pure audio signal for outputting time domain analyzed information. An analyzing unit(400) outputs first analyzed information related to the time domain analyzed information through pitch analysis, second analyzed information through formant analysis, and third analysis information through frequency domain analysis. A gram and characteristic factor extracting unit(500) displays the first to third analyzed information and extracts characteristic information. A characteristic factor fusing unit(600) fuses the extracted characteristic factors for outputting the same. A four-constitution discriminating unit(800) checks the output characteristic factors for outputs four-constitution analyzed information corresponding to the audio signal.
