Алгоритм измерения частоты основного тона речевых сигналов на основе комплементарной множественной декомпозиции на эмпирические моды
Abstract
The problem of measurement of speech signals pitch frequency is discussed. The existing pitch frequency measurement algorithms are presented, and the need to improve the measurement accuracy using adaptive processing techniques is proved. A new PF measurement algorithm based on the method of Complementary Ensemble Empirical Mode Decomposition is developed. The experimental studies of the developed algorithm are conducted, and the results prove the algorithm stability to the pitch frequency modulation and increase in PF measurement accuracy.
