R-colored vowels (also rhotic vowels, rhoticized vowels, retroflexed vowels, darn r vowels) are acoustically changed by an immediately following [r]. 

Expressive Cueing

The stressed vowel /ɝ/ (e.g., heard, bird, word) and the unstressed vowel /ɚ/ (e.g., blender, standard, ferment) are the only r-colored vowels in which a single cue (i.e., the mouth placement.) represents both the vowel and the following /r/. New cuers sometimes incorrectly add /r/ following this cue (e.g., */hɝrt/ for /hɝt/) especially in multi-syllabic words (e.g., */hɝri/ for /hɝi/).

The contrast betwen /i/ and /ɪ/ are important to differentiate English words (e.g., beat-bit, seat-sit, feet-fit). However, this difference is neutralized before /r/. In other words, there are no cases in the English language where changing /ɪ/ to /i/ before /r/ changes the meaning of a word. In fact, most speakers of English do not pronounce either vowel distinctly before /r/, but a sound somewhere inbetween. 

The vowel /i/ is a high front vowel. On the other hand, /ɪ/ is produced in a similar place in the oral tract, but with the height of the tongue slightly lower than for /i/. The vowel produced in “ear” words is, therefore, produced somewhere between /i/ and /ɪ/, and lowers as the word increases in length. For that reason the vowel will sound increasingly more ɪ-like in longer words. Compare the following: pier, piered, pyramid.

Further, the raising of the vowel /i/ tends to cuase insertion of a schwa resulting in the two-syllable /biɚ/. For instructional and reference purposes, many authors select /bɪr/ or /biɚ/. By far, /bɪr/ is the more common pronunciation. 

or”

A great deal of dialectal variation occurs in the American English pronunciations for “or” words. These words (e.g., sort, poor, core, mourn) may contain the vowels /ɔ/, /o/, /u/, or /ʊ/. Again, we see that the vowel contrast is generally neutralized before /r/. However, in some cases, the contrast persists. For cuers in parts of Louisiana, South Carolina, and New England, the words horse and hoarse may be pronounced distinctly.

For many regions, however, the distinction between /ɔ/ and /o/ is lost. In dialects of the mid-Atlantic region of the country (i.e., Virginia and Maryland) these words are likely pronounced with the vowel /o/ and cued with the side-forward movement. For most dialects in the country (and in most texts and dictionaries), the vowel is represented as /ɔ/. This is significant for Cued Speech instructors. Since, historically many of them come from a region dominated by /or/ while most of the country says and cues /ɔr/.

Cued Speech Instruction

For hearing students, recognizing vowel phonemes tends to be more challenging than consonants. The acoustic effect of a following [r] can make identifying vowels difficult. many instructors, therefore, devote specialized training to these vowels.
