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

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 ...

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

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 ...
