Syllables are shown in ARPAbet (the CMU Pronouncing Dictionary's phoneme alphabet). Respellings put the stressed syllable in capitals.

Why the count varies

Y/w glide formation. An unstressed i or u before another vowel (mill-i-on, It-al-i-an, on-i-on) is usually pronounced as a y glide, MIL-yun, which removes a syllable; careful speech keeps it.
