发明名称 TIME VARIABLE SPECTRAL ANALYSIS BASED ON INTERPOLATION FOR SPEECH CODING
摘要 A time variable spectral analysis for speech coding based upon interpolation between speech frames. A speech signal is modeled by a linear filter which is obtained by time variable linear predictive coding analysis algorithm. Interpolation between adjacent speech frames is used in order to express a time variation of the speech signal. In addition, interpolation between adjacent frames secures a continuous track of filter parameters across different speech frames.
