Journal ArticleDOI
YIN, a fundamental frequency estimator for speech and music
TL;DR: An algorithm is presented for the estimation of the fundamental frequency (F0) of speech or musical sounds, based on the well-known autocorrelation method with a number of modifications that combine to prevent errors.
Journal ArticleDOI
Restructuring speech representations using a pitch-adaptive time-frequency smoothing and an instantaneous-frequency-based F0 extraction: possible role of a repetitive structure in sounds
TL;DR: A set of simple new procedures has been developed to enable the real-time manipulation of speech parameters by using pitch-adaptive spectral analysis combined with a surface reconstruction method in the time–frequency region.
Book ChapterDOI
Pitch Perception Models
TL;DR: This chapter discusses models of pitch, old and recent, to chart their common points – many are variations on a theme – and differences, and build a catalog of ideas for use in understanding pitch perception.
Journal ArticleDOI
Denoising based on time-shift PCA
TL;DR: An algorithm for removing environmental noise from neurophysiological recordings such as magnetoencephalography (MEG) improves the value of data recorded in health and scientific applications by suppressing harmful noise, and reduces the need for deleterious spatial or spectral filtering.
Proceedings Article
Fixed point analysis of frequency to instantaneous frequency mapping for accurate estimation of F0 and periodicity
TL;DR: An accurate fundamental frequency (F0) estimation method for non-stationary, speech-like sounds is proposed based on the differential properties of the instantaneous frequencies of two sets of filter outputs based on fixed points of mapping from the filter center frequency to the output instantaneous frequency.
