Do guys know about their sleepy voice?

I’ve been taking to this guy online everyday for the past 2 weeks. We will be meeting soon and I’m kinda nervous lol. Anyways, it is clear he’s interested in me and hasn’t been playing any mind games with me and wants to talk everyday. I told him how I have insomnia and wake up around 4am and have trouble falling back asleep. He said I should call him next time it happens so that he could be awake with me and we could go through it together. Thought it was really sweet, lol. He said it again on our next phone call and said, “you would get to hear my sleepy voice too”. I’m interested to know if guys know that women are attracted to their sleepy voices and if he wants me to hear it so that I get turned on?
