Mechanical Speech Synthesizer is a real mechanical model of human's vocal production mechanism. Our vocal mechanism is composed of "Tongue", "Lips of mouth", "Vocal chords" and "Voice road" roughly separately. To realize these components, we should use some soft materials because they are basically constructed with the soft element. In this note, firstly, we introduce a brief history of speech synthesizer, and then show some importance of development of mechanical speech synthesizer. Next, we show some developed mechanical speech synthesizers. Finally, we discuss the next generation mechanical speech synthesizer.
