A voice lost is a voice that hasn't been used. Hoarse, broken, shady - not excess of use but a complete lack of use. Preceded by a brief attempt to reside in an octave that is not usually yours. Signaled by a breakdown of the system you know so well. Tongue, palate, vocal chords - all rendered useless - not by a misuse of power but by an ignorance of power.
That is when you are asked. You must, of course, be asked.
Do you know what would be said with the voice that has been lost? Do you want to know?
