How would you pronounce this name...?

Holly • 22 years old from Alabama. I have been married to my wonderful husband since Sept. 2012. We have a daughter. Our family was completed when our Son was born in November 2015.
So, was scrolling through my naming app, and I saw the Name Aislin. It says it's pronounces ash-lin, but I don't understand how! How would you say it?
