I say it more like [name_u]Gray[/name_u]-sin. Is it just me?
I say ‘gray-s’n’ Like the o doesn’t exist.
gray-sin
This is my cat’s name.
gray-sin
This is my cat’s name. I love the gray/grey names and also just [name_u]Gray[/name_u]/[name_u]Grey[/name_u].
I say it like gray-sin as well. Or if you prefer grace’n 
I have a lazy southern tongue though.
I pronounce it gray-sin.
I say gray-sun.
My cat is [name_m]Grayson[/name_m], as well ([name_u]Gray[/name_u]-sun).
I say it kind of like [name_f]GRACE[/name_f]-un. Definitely doesn’t sound like an ‘in’ sound to me, but that’s the wonder of accents The problems start for me when people start replacing Os with Is and Ys. It doesn’t translate properly into other accents; e.g. I’d pronounce Masin and Greysin differently to [name_u]Mason[/name_u] and [name_m]Greyson[/name_m] 
I say it gray Sin… You can always watch Revenge and see how they pronounce it.
Me too! I really prefer [name_u]Grey[/name_u]. [name_m]Grayson[/name_m] always sounds too feminine to me.
[name_f]Grace[/name_f]-un is the way I’d describe it as well. Same with most -son names : [name_f]Alice[/name_f]-un, [name_m]Harris[/name_m]-un, etc.
I think I say all the above, depending on the day, haha! I have heard myself say gray-son, gray-sin, grase-n, gray-suhn, etc.! Either way, I love the name.
I pronounce it [name_u]Gray[/name_u]-sin
grey-sn the O is still their but its just not very obvious.
I don’t know, but I’m thinking everybody says [name_m]Grayson[/name_m] the same way - [name_u]Gray[/name_u]-s’n.
Around here -son is always “sun.”
