Gianis mispronouncing gurmantar

I have heard quite a few granthi singhs speaking v(kanna) h(laan)-guru instead of v(kanna) h(sihari)-guru.
It is very important to do shudh ucharan of gurmantar as gurmantar is Gur-Moorat

True. Gurmanter should be the main part of our daily routine. Yet alot of people mispronounse it.
