论文摘要
在本文中，我们提出了基于多层感知器的语音编码的非线性预测矢量量化（PVQ）。我们还提出了一种评估量化器是否精心设计的方法，以及它是否利用了连续输出之间的相关性。尽管非线性PVQ的结果并不能改善非线性标量预测变量的结果，但我们检查是否有PVQ改进的空间。
In this paper we propose a Non-Linear Predictive Vector quantizer (PVQ) for speech coding, based on Multi-Layer Perceptrons. We also propose a method to evaluate if a quantizer is well designed, and if it exploits the correlation between consecutive outputs. Although the results of the Non-linear PVQ do not improve the results of the non-linear scalar predictor, we check that there is some room for the PVQ improvement.
