The accent is on the first syllable.
The "a" is an American English short "a", like in "tab" or "cat".
The "o" is barely pronounced. It's more of a vowel-sounding bridge between the "b" and "n".
The last syllable is pronounced like "knee".
"TAB(e)nee"
Tabony is my family name. I had the domain already, so used it for this site. My full name is Charles Joseph Tabony.
