Bismihi ta'ala
Our Islamic method of praying can only be recited in the Arabic language, making sure pronunciation is as best as possible.
If you are new to Islam, it is important to take gradual steps in familiarising yourself with the religion as much as possible, especially the doctrinal and moral aspects of the religion. As far as salah is concern, you must recite it in Arabic. You are able to read from a book, or follow a pra-along tutorial, or ask someone to assist you, until you memorise the blessed surahs and dhirks of prayer.
Of course, at the same time try to get to know the inner dimensions of prayer and also what the translation of what you are saying.
With prayers for your success.
