Are the names Emmy and Emma hard to distinguish for twins?

I’m pregnant my husband and I have been going Back and forth about our twin girls names. He likes the names I chose but says they’re extremely close to each other. Well I mean they’re twins that’s the point in my eyes. The names I’ve been going with are
Emma and Emmy or Amina and Amira
I’m not changing the names but are Emmy and Emma too close?
