Hi Yusuf,
There are only 4 vowels in Hebrew- א,ה,ו,י and you must know them.
I think you got confused and you meant niqqud.
If that's the case- then no. Even us the Israelis don't know it and hardly ever use it.
And besides, once you know a word, you know how to pronounce it correctly, so it's not really important.
If you need more help, please ask!
