Ah I see. About whether “Brahma” is pronounced as written or as “Bramha”, there is regional variation and difference of opinion even among the best scholars; recommended is to find a tradition and follow it. Overall M. S. Subbulakshmi's rendering may not be perfect but it's better than most, and if you can match it, it would be great. You can slow the playback if it's too fast; just tried it and at something like 0.7x speed it's still sounds fine while being slow enough. Anyway, you can look for recordings by people trained in Vedic recitation (not exactly same as priest…), like the Challakere brothers. Also, you may benefit from an actual class with feedback from teacher(s), etc; and Vyoma Labs (sanskritfromhome.in) have many "Learn to chant…" courses which are (incredibly!) free. Good luck!
