EVALUATION BASED ON 3D DISPLAS OF VOCAL VOWELS

T. Moriyama, H. Tsuda

Abstract

The aim of the study is the recognition on the voice-prints of vocal vowels using instrument and control engineering method in order to utilize for CIM, security system, the evaluation of the vocal training and the voice compensation for voice handicapped persons. The five stages evaluation on the vocal voice is decided by a professor of the department of music for the lived voice and output of DFT. The authors obtain three dimensional diagrams composed of the frequency, the spectrum and time using DFT.
