Pitch post-processing technique based on robust statistics
Yong Duk Cho, Khaldoon Al-Naimi, Ahmet M. KONDOZ · Electronics Letters · 2002
A novel pitch post-processing technique based on robust statistics is proposed. Performances in terms of pitch error rates and pitch contours show the superiority of the proposed method compared with the median filtering technique. Further improvement is achieved through incorporating an uncertainty term in the robust statistics model.
