Here's what might be intended:
* "Vowel and consonant": This is the basic distinction in speech sounds.
* Vowels are sounds made with an open vocal tract, allowing air to flow freely. They are typically the core of syllables. Examples: a, e, i, o, u.
* Consonants are sounds made with some obstruction of the airflow in the mouth. They often mark the beginning or end of syllables. Examples: b, d, f, g, h, j, k, l, m, n, p, r, s, t, v, w, x, y, z.
* "Vowel cluster": This term refers to two or more vowels that appear together within a word, such as in "diphthong" or "triphthong".
* "Consonant cluster": This refers to two or more consonants that appear together within a word, such as "bl" in "black" or "str" in "strong".
If you provide more context or the specific situation where you encountered "vowel consonant," I may be able to give a more specific answer.
