The formant with the lowest frequency is called F1, the second F2, and the third F3. (The fundamental frequency or pitch of the voice is sometimes referred to as F0, but it is not a formant.) Most often the two first formants, F1 and F2, are sufficient to identify the vowel.
How many formants are there?
Five formants are visible in this [i], labelled F1-F5. Four are visible in this [n] (F1-F4) and there is a hint of the fifth. There are four more formants between 5000Hz and 8000Hz in [i] and [n] but they are too weak to show up on the spectrogram, and mostly they are also too weak to be heard.

How many formants are in the voice?
The speaking voice tends usually, except with some classically trained actors and preachers, to have only two formants and not to have harmonics much in excess of 2500 Hz. The classical singing voice, however, has harmonics going up to 4000 Hz and beyond and has three more formants above the vowel defining ones.
