The role of formant-frequency contours in the perceptual grouping of speech formants.

The Journal of the Acoustical Society of America, 2011
The perceptual organization of speech remains poorly understood. Recent research using sine-wave speech suggests that the ability of an extraneous formant to impair intelligibility depends on modulation of its frequency contour [Roberts et al., J. Acoust. Soc. Am. 128, 804–817].

Formant frequency tuning in singing

Journal of Voice, 1992
Summary It is sometimes claimed that some singers tune their two lowest formant frequencies to harmonic partials in order to increase the audibility of the voice. Voice acoustics predicts that such tuning of formants should cause vowel quality to change.

Level and Center Frequency of the Singer's Formant

Journal of Voice, 2001
The "singer's formant" is a prominent spectrum envelope peak near 3 kHz, typically found in voiced sounds produced by classical operatic singers. According to previous research, it is mainly a resonatory phenomenon produced by a clustering of formants 3, 4, and 5.

Contributions of Fundamental Frequency and Formant Frequencies to Speaker Identification

Phonetica, 1975
Abstract 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, 1993
The 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 ...

Formant Frequency in Relation to Body Mass Composition

Journal of Voice, 2013
This 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 ...

Formant-frequency discrimination for isolated English vowels

The Journal of the Acoustical Society of America, 1994
Thresholds 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.

Mandarin Accent Analysis Based on Formant Frequencies

2007 IEEE International Conference on Acoustics, Speech and Signal Processing - ICASSP '07, 2007
Accent 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 ...

Method for extracting formant frequencies

The Journal of the Acoustical Society of America, 1990
A 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

Piecewise–planar representation of vowel formant frequencies

The Journal of the Acoustical Society of America, 1977
The 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).
