Corner vowels in males and females ages 4 to 20 years: Fundamental and F1-F4 formant frequencies.
Journal of the Acoustical Society of America, 2019 The purpose of this study was to determine the developmental trajectory of the four corner vowels' fundamental frequency (fo) and the first four formant frequencies (F1-F4), and to assess when speaker-sex differences emerge.

Kalman tracking of linear predictor and harmonic noise models for noisy speech enhancement [PDF]
, 2008 This paper presents a speech enhancement method based on the tracking and denoising of the formants of a linear prediction (LP) model of the spectral envelope of speech and the parameters of a harmonic noise model (HNM) of its excitation.

F0-induced formant measurement errors result in biased variabilities.
Journal of the Acoustical Society of America, 2019 Many developmental studies attribute reduction of acoustic variability to increasing motor control. However, linear prediction-based formant measurements are known to be biased toward the nearest harmonic of F0, especially at high F0s.

Volitional exaggeration of body size through fundamental and formant frequency modulation in humans
Scientific Reports, 2016 Several mammalian species scale their voice fundamental frequency (F0) and formant frequencies in competitive and mating contexts, reducing vocal tract and laryngeal allometry thereby exaggerating apparent body size.

Formant Estimation and Tracking using Probabilistic Heat-Maps [PDF]
arXiv, 2022 Formants are the spectral maxima that result from acoustic resonances of the human vocal tract, and their accurate estimation is among the most fundamental speech processing problems. Recent work has been shown that those frequencies can accurately be estimated using deep learning techniques.

The preposition potential in formation of conjunctional means [PDF]
Južnoslovenski Filolog, 2014 In the article the ability of preposition to form conjunction or its equivalent has been considered. The mechanism of denominalization has been shown on the Russian material with the involvement of the author’s observations on prepositions in ...

Formant Tracking by Computer [PDF]
The Journal of the Acoustical Society of America, 1959 At the last meeting of the Acoustical Society of America a method of formant tracking using a digital computer was described. By this method synthetic speech spectra, constructed within the computer from a catalog of elemental spectra, are compared with measured spectra of a speech signal.
