Abstract
LPC-synthesizing device, in which a modulation of the synthesized signal with a window signal is used to reduce the buzz which is characteristic for such devices. This window signal has an amplitude which initially increases gradually from substantially zero value to a constant value, and then decreases gradually from the constant value to substantially zero value. As a result of this modulation the signal in the transition between two segments of voiced speech is forced to zero thereby eliminating any transition discontinuities, the existence of which causes the buzz.
