Claim 19:
20. An apparatus comprising:
a voice accelerometer comprising:
a substrate;
a spacer layer supported over a first surface of the substrate; and
at least one cantilever beam element having a base portion that is supported over the substrate and spaced from the substrate by the spacer layer, wherein the at least one cantilever beam element includes a piezoelectric layer and a pair of electrically conductive layers disposed on opposing surfaces of the piezoelectric layer, wherein the at least one cantilever beam element has an electrical discontinuity in at least one of the pair of electrically conductive layers to provide an electrically active portion of the at least one cantilever beam element and an electrically inactive portion of the at least one cantilever beam element; and

a detector circuit configured to receive an output signal from the voice accelerometer and produce an output signal.
