The Genesis of Speech Synthesis in Japan
Japanese version is here
In order to study the acoustical cue of Japanese phonemes and syllables, speech sounds were synthesized and hearing tests were carried out at Radio Research Laboratories(RRL), Ministry of Postal Services, from 1959 to 1960. For those experiments, a terminal analog synthesizer electronically controlled was built by RRL.
