No, I will provide a soundfile. But I know that something is different because my voice USED to have a ring, and used to carry very easily and be very powerful, even when speaking. Now I can't even speak for too long before it starts to hurt or get very weak, let alone sing. I'm not really a trained singer but I know when something is off or different. Also, I would only get a reputable professional opera singer as a voice teacher, since that is my interest.

There are some clips..unfortunately I have no 'before' clips.......the choir director I had always said to use the 'ng' ring, so I know what it feels like and I know now that I don't have it anymore. Of course I'm not doing things right, but I don't even have the normal automatic resonance that any dumb idiot on the street has so that they can yell across the street.....e.g., in a crowded noisy room, I can't be heard because my voice just won't carry at all.
