Diese Energiekonzentrationen, die man im Sonagramm als waagerechte Frequenzbänder erkennen kann, heißen Formanten F1, F2, F3 und F4 etc. Bei der menschlichen Sprache charakterisiert die Lage der Formanten die Bedeutung bestimmter Laute. Vokale unterscheiden sich im Sonagramm von Konsonanten vor allem durch ihre deutliche Formantstruktur. Formant is a natural mode of vibration (resonance) of the vocal tract; a resonant frequency of the vocal tract Formants are identified by formant number (F1 F2 etc) and numbered in succession, with F1 as the lowest-frequency formant Each formant is described by two characteristics 1. center frequency (aka called formant frequency) f1 : f2 : f3 : f4 : f5 : tenor "a" freq (Hz) 650 : 1080 : 2650 : 2900 : 3250 : amp (dB) 0 -6 -7 -8 -22 : bw (Hz) 80 : 90 : 120 : 130 : 140 : tenor "e" freq (Hz) 400 : 1700 : 2600 : 3200 : 3580 : amp (dB) 0 -14 -12 -14 -20 : bw (Hz) 70 : 80 : 100 : 120 : 120 : tenor "i" freq (Hz) 290 : 1870 : 2800 : 3250 : 3540 : amp (dB) 0 -15 -18 -20 -30 : bw (Hz) 40 : 90 : 100 : 120 : 120 : tenor "o" freq (Hz) 400 : 800 : 2600 : 2800 : 3000 Se hela listan på F1 shows the highest values and the negative largest range of variation.

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. The parameters are explained in the text. The back vowels [o] and [u] are defined at increasingly low acoustic levels. The first formant corresponds to the vowel openness (vowel height). Open vowels have high f1 frequencies while close vowels have low f1 frequencies.

The progression from open to back produces a gradual reduction in the frequency of (F1), similar to results obtained elsewhere (Cf. Ladefoged, 1962).

The vertical lines indicate three potential time points of formant measurement: (a) near vowel onset, (b) midpoint, and (c) near vowel end.
