How do I change the Kiai Sound

I have uploaded a different file but the replay always says the previous one

Ensure the format is .wav

And make sure you click upload after you have selected the file, not just select the file

Also remember it shows "failed" message and "success" message at once if you succeed to change the kiai (it's a bug).

Also please check your kiai in game rather than by playing it in torishop - your browser cache could play the old sound while the new one is actually played in game.
