The sound is a compressional wave of air. Therefore, in the proposed circuit, the voice synthesis processing circuit is performed with a expression of pulse density. In our previous work, the voice synthesis processing circuit was represented as a triserial multistage registers. And we retrofit vocal tract circuit. It consists of bifurcated register circuits that modeling mouth orifice enlarging. We pay our attention to formant becoming the main factor to determine a vowel sound using the circuit.
