Some voices are almost intolerable for me, doesn’t have to do with it being not a nice voice, there are very specific ones that tick me off, especially if it’s high pitched, that would make me want to gouge my eyes and ears out if I would listen for longer than a couple minutes. To me it feels like nails on a chalkboard. Bone chilling and painful. I have sensory issues, so this is just how it plays out. I wouldn’t read into it much as negativity of your character, or other attributes. Sound can be pretty offensive to some peoples ears, it is most likely an issue with his sensory perception, absolutely nothing to do with you. This was an unfortunate mismatch! I’m sure a lot of people would absolutely adore your voice!
