Formant frequency estimation in noise

2004 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2004
This paper addresses the problem of formant frequency estimation of speech signals corrupted by colored noise. The spectrum is sequentially segmented into K segments so that each segment contains a single formant. A segmentation metric based on Wiener filter theory is proposed for determining the segment boundaries. A peak-picking algorithm is used for

A method for glottal formant frequency estimation

Interspeech 2004, 2004
This study presents a method for estimation of glottal formant frequency (Fg) from speech signals. Our method is based on zeros of z-transform decomposition of speech spectra into two spectra : glottal flow dominated spectrum and vocal tract dominated spectrum. Peak picking is performed on the amplitude spectrum of the glottal flow dominated part.

Formant frequencies in Middle Eastern singers

American Journal of Otolaryngology, 2008
This work was conducted to describe the formant frequencies in a group of Middle Eastern singers and to look for the presence of the singer's formant described in operatic singers.A total of 13 Middle Eastern singers were enrolled in this study. There were 5 men and 8 women.Descriptive analysis was performed to report the various formants (F1, F2, F3 ...

Formant Frequency Regions of Polish Vowels

The Journal of the Acoustical Society of America, 1967
Frequency regions of the first two formants of Polish vowels are given. The method included specification of these formants by spectral analysis of spoken vowels and by perceptual evaluation of synthetic vocalic stimuli.

Formant Frequencies of Stuttered and Fluent Vowels

Journal of Speech, Language, and Hearing Research, 1987
The formant frequencies of 15 adult stutterers' fluent and disfluent vowels and the formant frequencies of stutterers' and nonstutterers' fluent vowels were compared in an F1-F2 vowel space and in a normalized F1-F2 vowel space. The results indicated that differences in formant frequencies observed between the stutterers' and nonstutterers' vowels can ...

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.

Tracking of Speech Formant Frequencies

2006 IEEE 14th Signal Processing and Communications Applications, 2006
This study is about tracking of formant frequencies using Kalman filtering. Assuming that the formant frequencies are changing in time slowly, it is possible to model their behaviors as outputs of a dynamic system and then track them using Kalman filtering approach.

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].

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.
