Well I usually do this if I got crack in my voice, *Always drink water perhaps 1 glass *Sometimes I test my voice again with shout out loud but not forcing it *Try to remember to take a warm up then sing your voice with clearly rounded not flat... maybe these could help you!
if আপনি drink water, make sure its not cold water becuz it kills the vocals, also a উৎস of the reason for creaking is that perhaps the note is too high to hit just yet. take your time and don't stop warming up!
well what i do when i won a medal for গান গাওয়া i just payed attention to the person if your গান গাওয়া to someone অথবা if your গান গাওয়া দ্বারা yourself just pay attention to like the words find something to pay attention too
Well, আপনি should always warm up. Like গান গাওয়া do, re, me, fa, so, la, te, do and maybe doing a tounge twister. আপনি should also drink some warm water with some honey, অথবা some warm tea. আপনি could also eat something warm, I find that whenever I eat something hot/warm always makes my voice sound better. Hope this helps. :)
