Zeit-Frequenzinterpolation mit Anwendung zur Sprachkodierung mit niedriger Rate

摘要

A method for high quality speech coding is disclosed which offers advantages over conventional CELP (code-excited linear predictive) algorithms for low rate coding. The method, Time-Frequency Interpolation (TFI), provides a perceptually advantageous framework for voiced speech processing. The general formulation of the TFI technique is described.
