Fake it until you make it !
Someone famous said that. I personally attribute it to Milton Erickson, the father of the Ericksonian Hypnosis. He knew better 😉
So…
Let’s have fun… and exercise altogether !
Could you take any text in English and read it loud with a strong French accent ? Like v-e-r-y s-t-r-o-n-g !
Ridiculous ?
OK, not more than staying deaf in front of a text in French…
Playing the game of the French accent, you will get used to a lot flatter tonality, hardly any diphtongues, etc.
Just do it and have fun !
