The Formants of Fricative Consonants
Language and Speech, 1965Spectral analysis of American English, Swedish and Polish fricatives shows that these sounds may be classified according to the relations between their formant frequencies and formant levels. Three binary distinctive features at the acoustic-phonetic (not necessarily phonemic) level are postulated: spread/compressed formants (F4–F2); higher/lower ...

Vocal tract length and formant frequency dispersion correlate with body size in rhesus macaques.
Journal of the Acoustical Society of America, 1997Body weight, length, and vocal tract length were measured for 23 rhesus macaques (Macaca mulatta) of various sizes using radiographs and computer graphic techniques.

One of the principal problem areas in the perfection of the formant-tracker speech-compression system lies in the extraction with the utmost of precision of the formant traces that are pertinent to the preservation in speech of the articulatory events. Under a current research effort [sponsored by the U. S.

Source–filter theory assumes that calls are generated by a vocal source and are subsequently filtered by the vocal tract. The air in the vocal tract vibrates preferentially at certain resonant frequencies, called formants.

What’s wrong with these formants?
The Journal of the Acoustical Society of America, 2007Speech is frequently modeled as an all-pole (autoregressive) linear filter applied to a voice source, commonly called Linear Predictive Coding. This model has been used for many years to provide measurements of the resonance frequencies (formants) characterizing speech sounds.

Formant tracking with quasilinearization
ICASSP-88., International Conference on Acoustics, Speech, and Signal Processing, 1988An algorithm for the calculation of formant tracks from a speech signal is presented. It is based on the method of quasilinearization, a nonlinear parameter estimation procedure. What distinguishes this method from the most other methods is the fact that the formants are directly calculated from the speech signal, using a nonlinear model for the speech

The attempt to build a talking machine has a long history and can even be traced back to a time before the beginning of the Christian era (Linggard, 1985). The first complete talking machine is due to von Kempelen (1791) and is described in a book of over 400 pages that also reports on the twenty or so years of experimentation that were needed to build

The speaker's formant in male voices
Journal of Voice, 1997Spectral analysis of vowels during connected speech can be performed using the spectral intensity distribution within critical bands corresponding to a natural scale on the basilar membrane. Normalization of the spectra provides the opportunity to make objective comparisons independent from the recording level. An increasing envelope peak between 3,150

Purpose The use and study of formant frequencies for the description of vowels is commonplace in acoustic phonetics and in attempts to understand results of speech perception studies. Numerous studies have shown that listeners are better able to distinguish vowels when the acoustic parameters are based on spectral information ...

Evaluation of formant-based lip motion generation in tele-operated humanoid robots
2012 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2012Generating natural motion in robots is important for improving human-robot interaction. We developed a tele-operation system where the lip motion of a remote humanoid robot is automatically controlled from the operator's voice.
