A method which ensures credibility of the phonatory function test and accuracy of evaluation of phonatory function is now expected. We devised a phonation analyzer and reported as SK-80 which can record pitch, intensity and mean flow rate simultaneously and display these parameters on a CRT as two dimensional“voice profile”. However, it takes much time to record and display parameters with SK-80. To conquer this problem, authors developed a new program which analyzes data directly from SK-83 (new model of SK-80) . This program provides two dimensional “voice profile”automatically in a short time. Moreover, it can also calculate and display minimum mean flow rate and frequency distribution of mean flow.
