It is presumed that speech synthesis by rule will become increasingly important because of its wide applications. Speech synthesizer of formant analog type through this research is suitable for speech synthesis by rule, is simple in circuit configuration, and has the possibility of digitalization. The gist of this paper is as follows : (1) Study of configuration of resonant circuits that simulate formant composition and of formant transition characteristics results in improved quality of synthetic speech sound. (2) Through combined experiment on weather forecasts and nursery stories, qualitative characteristics in terms of fundamental frequency, amplitude, and period of duration are found, and simple contro rules about them are established. (3) An attempt of speech synthesis by means of a new method which combines both speech synthesis by rule and word editing system has led to an excellent result. (4) A comparatively good synthetic sound can be obtained by the amount of information less than 1/10 in comparison with the speech synthesis based on the PARCOR method.
