1. To speak softly, but loudly, with quite a bit of vibration to the vocal cords, not really caring about being overheard
2. The maximum volume of a whisper
3. When whispering just isn't loud enough

He was mad and tried to be quiet, but his whisper turned into a yellsper as his anger grew.

When someone thinks they are whispering, but do not realize they are doing even that loudly.

My son gets up super early and usually wakes us by yellspering to himself or at the dogs.
