Performance of articulatory parameters to express formant frequencies.

From formant frequencies to VT area function parameters

Formant trajectories for acoustic-to-articulatory inversion

This work examines the utility of formant frequencies and their energies in acoustic-to-articulatory inversion. For this purpose, formant frequencies and formant spectral amplitudes are automatically estimated from audio, and are treated as observations for the purpose of estimating electromagnetic articulography (EMA) coil positions. A mixture Gaussian regression model with mel-frequency cepst...

Vocal-tract area-function parameters from formant frequencies

The basic three-pararneter vocal tract area function model of Fant [2] has been extended to allow for asymmetry and variable length of the tongue hump section as well as variations of the VT overalllength. An important class of articulations are those that conform with this model, mostly vowel sounds and consonants wi~hout . apical . modification or a secondary posterior art1culatton. Starmg ou...

Formant Frequencies of Dutch· Vowels

In the present study Dutch vowel formant characteristics of laryngectomized tracbeoesophageal speakers are investigated.. Both vowels in CV nonsense syllables (/al, Iii, and /u/), and vowels of stressed syllables in read-aloud text are studied. It appeared that in the nonsense syllables the first formants were comparable to those ·of normal speakers, but that the second formants were higher tha...
