    Speech analysis and synthesis [Abstract]
    Tong, Y. C. ; Clark, Graeme M. ; Patrick, J. F. ; Gwyther, J. L. ( 1976)
    Speech sounds are digitized and stored in mass storage units of a Hewlett Packard computer system. A short-time frequency analysis of the speech sounds is then performed, and sound spectrographs are displayed on a Tektronix 4014 terminal. The speech sounds are also processed using a digital computer model of hasilar membrane motion, and envelope details of the cochlear analysis are displayed using the same technique as the sound spectrograph. Speech sounds are synthesized by rule using a hardward terminal analog synthesizer. A digital computer is used to translate a sequence of phonemes which comprise the speech sound into the control signals required by the synthesizer.
