Sefardi in an Ashkenaz Minyan

Dear Rabbi,

If a sephardic jew prays in a ashkenaz minyan and he got an aliyah, is he supposed to change the way he pronounces the words to a ashkenazic accent, or may he read the berachah in his sepherdic accent?

Thank You !!

Hi, You should use the sephardi pronunciation.

All the Best

Rabbi Shay Tahan
