提出了一种使用二维滤波器提取动态音调特征的新方法。由于面向 2D 的滤波器能够捕获音调方向，因此它们可以充分利用相邻帧的信息来提取动态音调特征，而无需知道音调或使用音调跟踪算法。实验结果表明，该方法可以产生良好质量的动态音调特征。
A novel method is proposed to extract dynamic tone features using 2D oriented filters. As 2D oriented filters are capable of capturing pitch orientations, they can make full use of the information from neighbouring frames to extract dynamic tone features without knowing pitch or using pitch tracking algorithms. Experimental results show that the proposed method can produce dynamic tone features of good quality.
