Представлены существующие алгоритмы определения этой частоты, разработан новый алгоритм на основе метода комплементарной множественной декомпозиции на эмпирические моды. Результаты исследований подтверждают устойчивость алгоритма к частотным модуляциям основного тона речевых сигналов.</p></abstract><trans-abstract xml:lang="en"><p>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.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>обработка речевых сигналов</kwd><kwd>комплементарная множественная декомпозиция на эмпирические моды</kwd><kwd>частота основного тона</kwd><kwd>speech signal processing</kwd><kwd>Complementary Ensemble Empirical Mode Decomposition</kwd><kwd>pitch frequency</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Михайлов В.
