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.
