摘要：
In contrast to the Linear Prediction (LP) all-pole model, the Minimum Variance Distortionless Response (MVDR) all-pole spectrum models voiced speech spectra very well. and features a smooth contoured envelope. Furthermore, the MVDR approach appears to be better suited for modeling unvoiced speech than LP method. We present a variable-order modeling method based on the MDR framework, and evaluate the performance of the method by experiment. The order of model is decided by the characteristics of speech frame in this method.
