A recent study suggests that musical consonance is based on harmonicity, a preference that reflects the central role of harmonicity in auditory perception.

In this paper, harmonicity information is incorporated into acoustic features to detect laughter segments and speech segments. We implement our system using HMM (Hidden Markov Models) classifier trained on Pitch and Harmonic Frequency Scale based subband filters (PHFS). Harmonicity of the signal can be determined by variation of the pitch and harmonics. The cascaded subband filters are used to ...

A fundamental structure of sounds encountered in the natural environment is the harmonicity. Harmonicity is an essential component of music found in all cultures. It is also a unique feature of vocal communication sounds such as human speech and animal vocalizations. Harmonics in sounds are produced by a variety of acoustic generators and reflectors in the natural environment, including vocal a...

Harmonic structure can be easily recognized in the timefrequency representation of speech signals even in the diverse environment. The harmonicity is a measure of the completeness of harmonic structure. This paper extends the use of conventional harmonicity measure to the tasks of pitch estimation and voice activity detection. A set of hierarchical harmonicities, including grid, temporal, spect...
