Abstract

Conventional sinusoidal and waveform interpolation coders have a modeling error that limits performance at high rates. In addition, their time-frequency localization of the unvoiced speech component is often insufficient to characterize the speech signal in a perceptually accurate manner. Both problems can be addressed with frame expansions. The use of frame representations, that are very similar to conventional implementations of the fore-mentioned coders, eliminates modeling errors. Furthermore, frame representations can be selected so as to preserve the time-frequency location of the unvoiced component even when it is characterized with statistical parameters only
