Abstract
The Laplace transform (s-plane) is obtained for contiguous or overlapping frames of speech (or other signals) and polepair parameters (frequency, damping, magnitude and phase) are selected for transmission so as to preserve maximum energy. Speech is reconstructed from the transmitted parameters, using, for example, a damped sine wave as the equivalent of a pole pair. No separate pitch determination is made, nor is a voiced/unvoiced decision required.
