Does anyone’s 14 month old not recognize their name ?

So we made the mistake of using multiple nicknames mixed with his name when addressing my baby and now I’m trying to get him to acknowledge his name 😩 also he says dada when he’s ready and somewhat of “mama” but that’s rare. He laughs at the games we play and also to his baby shows. We’re trying to get him to be more vocal. Any tips mama’s?
