PURPOSE: A method for analyzing a voice and a system thereof are provided to efficiently learn a language by measuring a pitch of a sound and visually expressing intonation. CONSTITUTION: A sound is inputted to a computer system. The strength of the input sound is measured. A pitch between the maximum values in the measured strengths is measured over a predetermined time interval. A reciprocal number of the measured pitch is set up as a pitch of the first time interval. A coordinate plane is displayed on a monitor, having a time axis as an X axis and a pitch as a Y axis. The set pitch is displayed on the coordinate plate to be corresponded to an intermediate point of the first time interval on the X axis. |
