We have already reported a stenographic typewriting system which can display the spoken Japanese to the hearing impaired people on a screen without delay and without abridgment. However, this system has some problems about the readabilities of the texts and the keystroke characteristics of the typewriter. New STENOPCON system.(STENograph OPerated speech CONversion system)has been developed as to overcome these problems. Much Chinese characters displayed in the texts, the automatic space characters insertion algorithm, the editing and correcting function for the mistakes or for the wrong stenographic conversions and the changing function of the character size have brought higher readabilities of the texts. The system has been experimentally demonstrated at some meetings of the hearing impaired people. The audience could easily understand the delicate and subtle expression of Japanese speech by the system. An improvement based on the measurement of operating force for the STENOPCON keyboard has been made. In order to verify this improvement an experiment has been undertaken using three stenotypists. We have found that they opearted the improved STENOPCON with fewer mistakes and with less fatigue than with the old model.
