How can I get my voice back and recover from hoarseness?

Ugh, been there, done that.

Have you tried resting your voice for a bit? If you've been sick recently, maybe your voice is "sick", so to speak, and you just have to wait for it to come back.

I agree with the first person: soup will help. Maybe peppermint tea.

Whatever you do, do not, I repeat, do not, force your voice to sing. If you do, you'll just end up straining your voice and then you'll never be able to sing well. It's happened before.

Like the others have said, rest is the best remedy. But, if these problems come back after a while, then you need to find a healthier way to sing because if you continue abusing your voice, you will eventually get vocal nodules and that is the end of your singing then! Therefore it is crucial to take professional singing lessons to just avoid any future problems with your voice! If the hoarseness is still there, say, after one week of TOTAL silence (no speaking unless it is absolutely necessary, no whispering, no singing!), then contact an ear-nose-throat specialist immediately.

If you need to shout (or amplify your voice), try to shout from the gut rather than the throat. It's difficult to explain, but try to use the most booming voice you can make loudly from deep down inside and it won't affect you as badly. That's what members of the Armed forces (especially Drill instructors/Parade commanders) are taught. It reduces throat fatigue. Of course, try this after your voice recovers (just give it time and try not to shout, the previous ideas are great).

Vocal rest. It can be annoying to stop talking for several days, but it really works. Also, Throat Coat tea works amazingly. It has a an annoyingly sweet after taste, but it actually helps. Wear a scarf - keeping your throat warm helps. But definitely do not push it.

Hot soup. And rest your voice for a day or two.

best i can say is let it rest, if you keep on singing it will just tear at your throat

unless you have a show

then you have to at least let the audience know

...haha don't ask
