text: In the binary classification of the American linguist R. Jakobson and others, vowels are distinguished according to distinctive features, as follows: compact vowels, in which the first formant is located closer to the second and third formants, and diffuse vowels, in which it is further removed from the remaining formants; low vowels, in which the second formant is located nearer to the first, and high vowels, if it is nearer to the third; sharp vowels, which are characterized by a rising of the second and higher formants, and unmarked vowels, which do not have this increase; flat vowels, in which all formants shift downward, and unmarked vowels, which do not have this feature; and tense vowels, which differ from lax vowels by a greater deviation of the formants from a neutral position.
