Distinction Between EMD & EEMD Algorithm for Pitch Detection in Speech Processing
Bhawna Sharma, Sukhvinder Kaur · International Journal of Engineering Trends and Technology · 2014
In this paper we describes the different algorithms for finding pitch markers in speech signal and it also explain how EEMD is better than EMD algorithm One of the major problem in EMD algorithm is mode mixing. EEMD algorithm helps in solving mode mixing problem. EEMD algorithm is a noise assisted data analysis (NADA) for extracting pitch information for the speech signal. In EEMD signal is decomposed into intermediate functions called IMF. Using these IMFs, information regarding pitch markers can be evaluated. Keywords— EMD, EEMD, IMF, NADA.
