Circuit arrangement for synthesis of acoustic elements

Claim 1

A circuit for the production of artificial speech from acoustic elements comprising signal generator means for supplying a signal having a wide spectrum of frequencies and amplitudes, coordinate control matrix means having a plurality of input conduits and a number of intersection points, signal selector means for connecting said input conduits to said generator means, a potential field device comprised of an electrically conductive medium having a plurality of regularly arrayed spaced apart input electrodes and a plurality of spaced apart output electrodes connected thereto, whereby the potential at a given output electrode is a function of potentials applied to said input electrodes and the geometry of said medium between said output electrode and input electrodes to which potentials are applied, means coupling said input electrodes to said intersection points for providing a potential distribution of said signal along the output electrodes in response to the signals applied to said input conduit by way of said selector means, a plurality of bandpass filter means coupled to said output electrodes to select the magnitude of a spectral portion of the signal as determined by the action of said potential field device, and means for coupling the outputs of respective filter means to produce a synthesized sound spectrum.
