My name is Ghislain and the pronunciation in French is a soft G pronounced like the French letter J. To help pronounce the first part of the name, clench your teeth together and speak the g with the French letter I which sounds like and English E. Like the actress Zsa Zsa Gabor, but instead of an a put an English e Zse Zse. So add the s to sound Zses and the end is similar to lay. This end is more difficult to explain, since I can't think of any English word that is exactly like it. I might try at another date.
