Toure joined Foxes boss Brendan Rodgers' backroom team last year.
"He was very young when he came over to England as well," Soyuncu told Sky Sports. "He's shared his experience with me, the difficulties he had when he first arrived. It helps to listen.
"Being in Germany before coming to England made it slightly easier to adapt but Kolo, my team-mates, lots of people at the club have helped me.
"We all make mistakes... and he tells me when I make mistakes! But he also shows me where I have done well. He's played for his national team, played in the Premier League and had a great career. So I'm lucky that he plays the same position."
