Reading the name like this "Arh- ni - kha" I pronounce it exactly as you want it pronounced

Reading it like Anika, i pronounce it how everyone else is pronouncing it.

So all i think you need to do is change the spelling

No need to give up a name you love

What about Chardonnay, Serenity, Tia, Ocean (OH SHEE ARN), Blessing, Sapphire, Briella, Satarrah.
