Robust dynamic tone feature extraction using 2D oriented filters

摘要

A novel method is proposed to extract dynamic tone features using 2Dudoriented filters. As 2D oriented filters are capable of capturing pitchudorientations, they can make full use of the information from neighbouringudframes to extract dynamic tone features without knowing pitch orudusing pitch tracking algorithms. Experimental results show that theudproposed method can produce dynamic tone features of good quality.
