Do I have a lisp?

Do I have a lisp? I have suffered from a sever stammer from age 7 to 18. But I afraid that I started to observe different impediments in my speech more I listen to it. I can't roll my R's (which is not very uncommon) and I think I have a lisp on S. How can I cure it? My voice ("To be or not to be" in Turkish): [https://voca.ro/1flHGdcMTmhn](https://voca.ro/1flHGdcMTmhn) I will study Speech Pathology in university and I am pretty anxious, this is important to me!
