noun
syllable
SIL-uh-bul/ˈsɪləbl/
A unit of speech organized around a single vowel sound.
Each clap marks one syllable in the word 'apple.'

Etymology
“Together” and “take” express the image of gathering sounds or letters into one unit. A syllable is that grouping understood as a single effort of pronunciation.
In context
we have the vowel sounds o and i because they are successive and they occur inside the same syllable so we consider them one sound
