Fundamental Frequency Estimation by Harmonic Identification
T. B. Snow, G. W. Hughes · The Journal of the Acoustical Society of America · 1969
A novel method of fundamental frequency estimation is presented utilizing the inherent line spectrum characteristic of the speech signal. After finding the strongest harmonic in a limited frequency range, a computer program determines and examines the expected positions of lower and higher harmonics and assigns the proper harmonic number. An array of previously measured filter responses provides a frequency estimation of the identified harmonic. Two adjacent harmonics are necessary for proper identification, but the fundamental component need not be present in the limited filter bank range. The range of frequency estimation is limited only by hardware and is 75
