Contributions of Fundamental Frequency and Formant Frequencies to Speaker Identification
Phonetica, 1975Abstract This experiment in aural speaker identification attempts to ascertain the relative contributions of fundamental frequency and formant frequencies. Speech samples were four voiced, whispered, and low-pass filtered isolated vowels produced by eight male speakers.

Formant tones: weak components at formant frequencies actively generated in the vocal tract
IEEE International Conference on Acoustics Speech and Signal Processing, 1993The authors have discovered the presence of weak sinusoidal components located at formant frequencies in voiced speech segments. They refer to them as formant tones and propose a method to estimate and track the frequencies of these formant tones. These sinusoidal components are often located close to the strongest harmonic component under the formant ...

Piecewise–planar representation of vowel formant frequencies
The Journal of the Acoustical Society of America, 1977The first three formant frequencies for 778 steady-state tokens of 30 nonretroflex vowel types uttered by a female speaker are found to lie close to a piecewise–planar surface (expressed numerically as 0.634F1+0.603F2−0.485F3−366=0, for F2≳0.027F1+1692 and 0.686F1−0.528F2−0.501F3+1569=0, otherwise).

Mandarin Accent Analysis Based on Formant Frequencies
2007 IEEE International Conference on Acoustics, Speech and Signal Processing - ICASSP '07, 2007Accent analysis for Mandarin Chinese based on formant frequencies is presented in this paper. Five monophthongs [a, o, e, i, u] of 430 speakers across eight accents were analyzed with univariance analysis of variance (UNIANOVA). The results show that accent has significant influence on the second formant frequency of monophthongs [o, i, u] and has no ...

On the Separation and Measurement of Formant Frequencies
The Journal of the Acoustical Society of America, 1956A method of separating and measuring formant frequencies is described. The procedure is based on various weightings of the short-time power spectrum of the speech wave to be analyzed [Chang et al. Proc. Inst. Radio Engrs. 39, 147 (1951)]. The performance under a variety of disturbances such as noise, spurious pulses, and low-frequency distortions is ...

Formant Frequency in Relation to Body Mass Composition
Journal of Voice, 2013This study examines the relationship between total body mass composition and vowel formant frequency and formant dispersion in men.A total of 60 healthy male volunteers were recruited. Formant frequencies and dispersions of F1, F2, F3, and F4 for the vowels /ɑː/ and /iː/ were determined using spectrographic analysis.The mean height and weight were 179 ...

Method for extracting formant frequencies
The Journal of the Acoustical Society of America, 1990A high speed method for formant extraction includes the steps of calculating linear prediction coefficients by executing linear prediction analysis of an input speech signal, extracting a coarse formant frequency by making a linear combination of multiple regression coefficients obtained through multiple regression analysis executed with speech feature

Formant-frequency discrimination for isolated English vowels
The Journal of the Acoustical Society of America, 1994Thresholds for formant-frequency discrimination were obtained for ten synthetic English vowels patterned after a female talker. To estimate the resolution of the auditory system for these stimuli, thresholds were measured using well-trained subjects under minimal-stimulus- uncertainty procedures.

Frequency Detection and Speech Formants
The Journal of the Acoustical Society of America, 1951This study is aimed primarily at evaluating the utility of axis-crossing detectors in tracking speech formants. Detectors of the usual type are found subject to an error, fundamental in nature. To remove this source of error speech is modulated up in frequency as a single sideband before limiting and detecting processes are applied.

Discrimination of Formant Frequency Transitions in Synthetic Vowels
Journal of Speech and Hearing Research, 1973Discrimination of second-formant (F 2 ) transitions in synthetic vowels was measured with and without the first formant (F 1 ) present, with and without a transition in F 1 , and with F 1 at various amplitudes relative to F 2
