The speech synthesizer operating with an electronic computer is designed to control by a digital computer through control circuits the vocal tract which is simulated by an ultra high speed analog computer. This report explains especially the control system of the speech synthesizer and its practical side. First of all, in case of synthesizing some Japanese sentences, we spell and set those in Roman letters and we appoint the buzz pitch, the duration and the stress of each syllable, and the space of time to a next syllable. The information of each syllable is manifested by the control signals of 20 bits, in the digital computer. Once the order of speaking is issued, the control signals of the first syllable are sent through the shift register to the set register, to the control circuits, which receive those signals and send many configuration parameters to the simulator. And when the signals to control buzz and hiss sources are sent, then the simulator will synthesize the syllable. After it ends, the signals of a next syllable are sent again to the shift register and the syllable is synthesized. Thus synthesis of continuous speech by this kind of device is quite possible. At present, through this appalatus, a song synthesis is put into practice, too.
