How would you pronounce the name LJUPKA?

[MadreInglese]

I have to phone a lady called Ljupka, any ideas how to pronounce it?

I'm thinking something like loop-ka but not sure!

Lee-oo-pka

I'd probably guess something like LeeYupKa, but I'd probably apologise and ask how to pronounce it properly

loopka, i would guess it is a silent J.

Yoopka? or Leeyoopka?

The "j" may sound like a 'y' so Leeupka

Lyoupka

Leyupka?

Well she pronouced it for me when she answered "Leeyouka speaking" (it's croatian apparently)
