English Phonetics/Rhotic vowels

The English phonetic also includes including 6 r-colored or rhotacized vowels. These ones are used mainly used for the vowel + R combinations. These vowels are modified by the R that follows them, incorporating to them and forming a single unit, as it's in the case of the diphthongs.

Like the diphtongs, these ones may vary their pronunciation, according the dialect, depending strongly if the voice provider has a rhotic accent or not. Considering this, these R-colored vowels may can be realized as a diphthong that end in schwa or a long monothong, in the case of the non-rhotic accents, or as true rhotized vowel or as a vowel/diphthong that ends with a notorious R, in the case of the rhotic accents.
