Formant frequencies in Estonian folk singing

The Journal of the Acoustical Society of America, 1992
Formant frequencies in an old Estonian folk song performed by two female voices were estimated for two back vowels /a/ and /u/, and for two front vowels /e/ and /i/. Comparison of these estimates with formant frequencies in spoken Estonian vowels indicates a trend of the vowels to be clustered into two sets of front and back ones in the F1/F2 plane ...

Measurement of formant frequencies and bandwidths in singing

Journal of Voice, 1995
That singers under certain circumstances adjust the articulation of the vocal tract (formant tuning) to enhance acoustic output is both apparent from measurements and understood in theory. The precise effect of a formant on an approaching (retreating) harmonic as the latter varies in frequency during actual singing, however, is difficult to isolate. In

Estimation of formant frequencies in infant cry

International Journal of Pediatric Otorhinolaryngology, 1995
The formant frequencies (F1, F2, F3) of normal infant crying were measured using three different estimation techniques: sound spectrography, linear predictive coding (LPC), and power spectrum analysis. Results found all three techniques to be highly similar for estimation of F1. However, the techniques differed significantly in the estimation of F2 and

Formant Frequencies and Dentofacial Anomalies

2021
Formant frequencies are used commonly in the estimation of body size and dentofacial morphology. Their predictive value is derived from the strong link between body skeleton, cephalo-facial anthropometry, and vocal tract development. Patients with dentofacial anomalies often display alterations in vocal tract dimensions leading to distinctive acoustic ...

Formant frequencies in country singers' speech and singing

Journal of Voice, 1999
In previous investigations breathing kinematics, subglottal pressures, and voice source characteristics of a group of premier country singers have been analyzed. The present study complements the description of these singers' voice properties by examining the formant frequencies in five of these country singers' spoken and sung versions of the national

Formant Frequencies of Malay Vowels Produced by Malay Children Aged Between 7 and 12 Years

Journal of Voice, 2012
The formant frequencies of Malaysian Malay children have not been well studied. This article investigates the first four formant frequencies of sustained vowels in 360 Malay children aged between 7 and 12 years using acoustical analysis. Generally, Malay

Predicting Formant Frequencies from MFCC Vectors

Proceedings. (ICASSP '05). IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005., 2006
This work proposes a novel method of predicting formant frequencies from a stream of mel-frequency cepstral coefficients (MFCC) feature vectors. Prediction is based on modelling the joint density of MFCCs and formant frequencies using a Gaussian mixture ...

MAP prediction of formant frequencies and voicing class from MFCC vectors in noise

Speech Communication, 2006
Novel methods are presented for predicting formant frequencies and voicing class from mel-frequency cepstral coefficients (MFCCs). It is shown how Gaussian mixture models (GMMs) can be used to model the relationship between formant frequencies and MFCCs.
