The OY vowel sound sounds like the long vowels O-I-E.

There are 3. Epsilon ("e" sound in "get") Omicron ("o" sound in "hop") Upsilon ("u" and "y" sounds)
The letters 'c' and 'z' make the 's' sound.:)
In the word "plight," the letters "i" and "g" have the long "i" sound.
"the word of the sound of your voice with four letters" is grammatically incorrect.
The letters "ou" make the "f" sound in the word "rough."
Good choices if your thinking is sound, and bad choices if your thinking is weak.
3 if you count the vowel sound (which is the diphthong e-i) as one phoneme, which is standard. N-ei-m. There are 4 letters in the word but only three sounds. Phonemes are sound units not letters: the word "though" has six letters but only two phonemes.
