dc.description.abstract | The paper examines several pitch estimation and adaptation algorithms in forward and backward adaptive CELP systems. The authors compare open-loop and closed-loop pitch estimation structures, the use of integer and non-integer delay pitch prediction, and the implementation of block adaptive and sample recursive pitch tracking algorithms. Forward adaptive systems are found to perform better with a closed-loop structure in conjunction of non-integer delay pitch prediction. However, temporal and noise feedback problems suggest that open-loop structures with hybrid pitch tracking are better suited for backward adaptive systems. | |
