I'm a good singer, but my sis claims she's better. I KNOW i'm better. What can I do? Please help!!!

Just ignore her. I know it's hard, (trust me, I grew up in a house of 7 kids) but sometimes it's what bạn gotta do. As long as bạn have confidence in yourself, that's really all that matters.

But, if you're serious about proving who's better, bạn could have a contest. Each of bạn sing to a randomly selected friend/relative and let them decide. Or, if bạn don't like hát in front of people bạn could record yourselves.

There is really nothing bạn can do if someone is being immature in that way. Ignore her. bạn have nothing to prove.

Do a hát contest to know which one's better. hoặc record both of your voices hát and judge which one's better.

have a hát duel challenge her have your Những người bạn and family choose

Just say "You know what! That is super mean whether I am a good singer hoặc not! How would bạn like it if I called bạn a bad singer hoặc đã đưa ý kiến bạn sing of key?"

Have a contest, and let who eva is watching decide! prove yo sis wrong and hiển thị off yo talents!!!!

Don't fret! No offence, but it's just a voice! It doesn't matter who's better, what matters is that you're both awesome in your own unique way!
