Interharmonics frequencies are not integer multiple of the fundamental frequency, and interharmonics amplitudes are far less than fundamental amplitude and harmonics amplitudes, which mean high sensitivity to desynchronization problems, so it’s dificult to estimate interharmonics. In this paper, a new method based on random sparse sampling and compressed sensing (CS) Bregman technique was propo...

BACKGROUND Models of honest advertisement predict that sexually selected calls should signal male quality. In most vertebrates, high quality males have larger body sizes that determine higher social status and in turn higher reproductive success. Previous research has emphasised the importance of vocal tract resonances or formant frequencies of calls as cues to body size in mammals. However, th...

A Modeling Approach for Electric Power Transmission Lines in the Presence of Non-Fundamental Frequencies Valentina Cecchi Karen Miu, Ph.D. In light of the fact that modern power systems are expected to exhibit an increased level of harmonic and inter-harmonic frequency components, a modeling tool for electric power transmission lines was developed to determine the appropriate model structure un...

In natural speech, there is a moderate correlation between the fundamental frequency and formant frequencies across talkers. The present study used a high-quality vocoder to manipulate these properties and determine their contribution to perceived naturalness and voice gender. The stimuli were re-synthesized sentences spoken by two adult males and two adult females. Scale factors were chosen fo...
