| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Human various voices are made by a shape of a phonatory organ that changes its complexity with the muscles. In this paper, we construct virtual physical space with a logical circuit in an FPGA, that perform acoustic propagation, reflection and superposition, and the circuit simulates the function of phonatory organ. The sound is a compressional wave of air. Therefore, in the proposed circuit, the voice synthesis processing circuit is performed with expression of the pulse density. In our previous work,the voice synthesis processing circuit was represented as a triserial multistage registers. In this work, we retrofit vocal tract circuit. It consists of bifurcated register circuits that modeling mouth orifice enlarging. By representing bifurcated register circuits, more complex sound wave superposition become possible. Finally, we report about sound variation generated from the proposed circuit and circuits operation. |
