When can Dad talk to baby?

Nicole • Forever missing my angel baby 👼🏻❤️ my rainbow baby girl Juliet was born March 15, 2019! 💗🌈

I’ve heard 16 weeks, 18 weeks and 23 weeks is when the dad can start talking to the baby. I always personally thought starting at 18 weeks the dad can talk to the baby, does anyone know the legitimate time when my baby’s father and other family can begin speaking to the baby ? Me as well of course !
