In the conceptualization of the four long vowels above, uniskript glyphs employ the following visual-featural indexicality and sound-shape congruency correspondences:
- The extra length of the vowels is reflected visually through the juxtaposition of two glyphs.
- The number of lines represents the degree of opening of the mouth at the beginning of the articulation of the vowel.
- The half hexagon in on the right side represents the raising of the center of the tongue at the end of the articulation of those long vowels.
- The curve in the right side of the first glyph represents the backness of the vowels. An angle at the left side of the front closed vowel represents sharpness.
Consonant with the evidence found in the sound-symbolism literature, and as a general rule in the uniskript representation of long vowels, sharpness is associated with long vowels ending in an "i-like" sounds and roundness is associated with long vowels ending in a "u-like" sounds.
Stops and Affricates
Let us now examine the English consonants organized according to their phonological features and cross-modal correlations. The first chart introduces all the plosive consonants, including the affricates. For each consonant, the chart in Figure\ref{672041} shows the relevant phonological features in the first column, the uniskript glyph in the second, the phonological segment using IPA, a common grapheme using in the English orthography to represent the sounds, and a keyword.
