An Algorithm for Measurement of the Pitch Frequency of Speech Signals Based on Complementary Ensemble Decomposition Into Empirical Modes

Abstract

The problem of increasing the precision with which the pitch frequency of speech signals is measured is considered. Existing algorithms for determining this frequency are presented and a new algorithm based on complementary ensemble empirical mode decomposition is developed. The results of the investigations confirm the robustness of the algorithm in the presence of frequency modulation of the pitch of speech signals.
