Abstract (en)

[origin: EP0051462A2] A system and apparatus for generating human speech or other complex sounds from a digital command signal and using a hybrid synthesis technique comprises a digital, fixed repertoire speech processor (10) which includes a first circuit (12) for modeling the behaviour of the human vocal tract and a second circuit (11) for controlling the behaviour of the modeling circuit (12). The processor may advantageously be implemented on a single VLSI integrated circuit chip.
