AI voices change through the capsule

Hi, I've started using Liam as a voice for my capsule.  My text is in French and it sounds nice with a small accent for France.  I'm from Quebec, where our accent is different.  I've started with the accent from France which was fine but in the middle of my capsule, Liam starts to have an accent from Quebec... I like it, but why has it changed through my work?  I didn't touch anything.  I would like to stay with the same accent...
