Oh my god! My S/o & baby relationship!!

My S/o woke me up by speaking to my stomach. He was speaking and the baby was kicking and responding to his voice!!! I'm 22 weeks and it was unreal!! It's my first baby! My boyfriend put his phone music on my belly and the baby kicked even harder !! When he stopped speaking and playing music, he went back to sleep! He actually does listen! Is this what I think or is, or is it a coincidence maybe...?
