There was no significant difference in any of the other
formants of F1, F2, F3, and F4 for vowels /a/, /[epsilon]/, h/, /oe/, /u/, and /y/ (Table 2).
This decreased number of available harmonics, when coupled with fewer
formants (due to the shorter vocal tract present in most treble singers), result in different acoustic situations.
The
formants appear as horizontal frames; instead of that, amplitude values in function of frequency are represented in a gray-scale in vertical sense.

The second variable is the
formant centralization ratio (FCR), which is a coefficient that represents the magnitude of centralization of the
formants F1 and F2 for vowels /i/, /u/, and /a/.
The mid cursor indicates the middle of the
formants at which measurement of the
formant frequencies are taken in Hertz (Hz) while the two extreme cursors measure the duration of the vowel from the beginning of the sound (left) to the end (right) in seconds.
Further to put
formants in the KLAT synthesizer, we used WAVESURFER instead of PRAAT for
formant estimation because
formants estimation from WAVESURFER is easy to find than PRAAT, but we record my sound in the PRAAT.
where [y.sub.1,2] represent values of PSD in [dB] of determined
formants, and [x.sub.1,2] are the positions of the
formants on the frequency axis in [Hz].
In this regard, Weisman and Martin (1992) studied the trajectory of vowel
formants and found that F2 is the
formant that establishes the most direct relationship with the degree of speech intelligibility.
The calls were distinguished between one another by their "
formants," a term that is usually applied to the vocal tract resonance that makes one human voice sound different from another.
Issues concerning vocal technique include coordinated onset and release of sound, breath management, vibrato, agility, resonance, laryngeal,
formants and the singer's
formant, articulation, vowel modification, sostenuto, dynamic control and messa di voce and hearing, feeling and seeing the voice, warming up and cooling down the voice, and the spoken voice.
The study found both mice and human mothers were sensitive to the same structural elements - or
formants - within those sounds.
To make abstract technical decisions more concrete, science writers often examine the personal choices of their technical in
formants ("Would you live at Love Canal?"), undermining the idea that technical decisions are based on depersonalized evidence.
Vocal tone is therefore a blend of the tone colors of the harmonics being featured by its resonances (
formants).
