Reading the Quran and famously narrated duas are recommend to be recited in the original Arabic language. This way the meaning stays the same and the real spiritual feeling may be gained by reciting them exactly how they have reached us.
If however a person isn’t able to read them in the original language, he still may do it in his own language with a pure intention to the best of his ability.
In Al-Kāfī we find the following narration where the prophet (sawa) states:
“The non-Arab from my community should recite the Quran by his own language, for the angels will raise it to Arabic”
May Allah grant you success
