(Vertical lines represent 1000 Hz increments) The vowels differ systemtically in the frequencies of the first two formants (F1 and F2): [i] has low F1 and high F2. [a] has high F1 and low F2. [u] has low F1 and low F2. Most of these formants are produced by tube and chamber resonance, but a few whistle tones derive from periodic collapse of Venturi effect low-pressure zones. The formant with the lowest frequency is called F1, the second F2, and the third F3. Most often the two first formants, F1 and F2, are sufficient to identify the vowel. F1 : first formant : 500 Hz : F2 : second formant : 1500 Hz : F3 : third formant : 2500 Hz F1: The first formant (F1) in vowels is inversely related to vowel height, i.e. the higher the formant frequency, the lower the vowel height (and vice versa). Figure 2. 5 Notes: Red indicates high vowels with low F1; Blue indicates mid/low vowels with high F1 The frequencies of F1 and F2 generated by the three parameter model for the four preferred constriction locations, based on nomograms by Stevens and House (1955, Development of a quantitative description of vowel production, Journal of the Acoustical Society of America, 27:484-495); distance from source to constriction 12cm for the hard palate, 8.5cm for the soft palate, 6.5cm for the upper pharynx, and 4.5cm for the lower pharynx.
A further aim was to determine if F1 amplitude or frequency was more important in determining benefit and if F1 benefit varied with formant … Thus the first formant F 1 has a higher frequency for an open vowel (such as [a]) and a lower frequency for a closed vowel (such as [i] or [u]); and the second formant F 2 has a higher frequency for a front vowel (such as [i]) and a lower frequency for a back vowel (such as [u]). as can be seen in Fig. 1. Formant frequencies of English vowels. Filter functions for the set of English vowels are shown next to the vocal tract images in this figure. The vowels in the left column are called "front vowels." Tongue body is in the front of the mouth. All vowels show a "gap" in frequency between F1 and F2. The frequency of the first formant is mostly determined by the height of the tongue body: high F1 = low vowel (i.e., high frequency F1 = low tongue body) low F1 = high vowel (i.e., low frequency F1 = high tongue body) 2017-09-01 · Figures 1 and 2 show two F1/F2 vowel diagrams. Since the 1950s, it’s been customary to interpret F1 as tongue height, and F2 as tongue position, with reference to the Bell vowel model (Sidney Wood, 1982, X-Ray and Model Studies of Vowel Articulation, Working Papers 23, Department of Linguistics, University of Lund; and The Bell vowel model on this website).
In each case the formant values of female speaker is comparatively high than the male speaker. The reason is that the required widening of the pharynx and the lowering of the larynx also affect F1 and F2. Sundberg (1970) measured formant frequencies in vowels sung by four singers and compared these frequencies with formant frequencies reported for nonsingers by Fant (1973).
and stress (stressed vs unstressed vowels) on vowel formants F1 and F2, vowel duration, and fundamental frequency (f0). 45 female speakers were recorded:

fundamental frequency from formant frequencies. Formant frequency is symbolized as Fi, where F is the center frequency of the formant and i is the formant number. For example, F1 is the first formant frequency. Bandwidth is symbolized as Bi where B is formant bandwidth and i is the formant number. For example, B1 is the first formant bandwidth.
Gilbert HR(1), Robb MP, Chen Y. Author information: (1)Department of Communication Sciences, University of Connecticut, Storrs 06269, USA. Developmental characteristics of formant 1 (F1) and formant 2 (F2) are reported for spontaneous vocalizations produced by four young children. first formant frequency of a vowel primarily resides in this frequency range and usually has a greater amplitude than the fundamental frequency, the M100 latency tends to index F1. Moreover, the M100 timing does not seem to be based on a broader range of information about the vowel spectrum.

/a/ has a high F1 (@ 800 Hz) and a close F2 (@ 1,000 Hz) The vowel for "who'd", ooooooo or /u/ Container 1 (behind the tongue) is large. Container 2 (in front of the tongue) is large.
the higher the formant frequency, the F2: The second formant (F2) in vowels is somewhat related to degree of backness, i.e. the more front the vowel, the F3: The lower of the formant 2013-03-08 · How to Find Formant Frequencies in Praat: Select the mid-point of the vowel and go to the “Formant” menu above.
