I uploaded a few voice lines and while some of them allow me to distribute on the creator store, one in particular won’t let me at all?
I even tried editing the file a bit and reuploading but it still won’t allow me to distribute my own audio on the creator store
Is there anything I can do about this?
If the audio is more than 10 seconds long (i think this many seconds, not sure), the only way to distribute it is to prove you own that sound by contacting roblox support
The audio is only 3 seconds long 
Right now, voice lines (or anything with speech) are not considered a sound effect (confirmed by Roblox).
I am not sure if this is exactly true, but the system detecting the speech may have been a reason one or more of your assets don’t qualify.
