First syllable is Yo, with a short "o" as in "orange".
Second syllable is "che" - the ch is agutteral, at the back of the throat, kind-of like claring your throat. There isn't an English equivalent, and I can't think of a better way to explain it in text! The "e" is the same sound as the beginning of "egg".
The last syllable is "ved", with the same "e" as in "egg".
The stress on the word falls on the middle syllable - "che"
